    Cirkulär ekonomi: Vad påverkar kommuners arbete med den ekonomiska modellen?2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study was to examine and compare what causes some municipalities to work with and market their sustainability work in circle economy and what causes some other municipalities not to do so. The study focused on six municipalities, three who worked with and marketed their sustainability work and three who didn’t. Through telephone interviews a representative from each municipalitiey answered; how they defined circular economy, what drove/not drove them to work with circular economy, what difficulties there is with circular economy in the public sector and how the municipalities work can be improved. The results showed that the definition of the economic model was about the same, what differed was their knowledge about the importance of product design. Knowledge and interest in circular economy was two of the causes of why municipalities worked with the model. The fact that the issue was not a priority and the lack of resources from politicians seemed to be two determining factors of why the municipalities’ interest in working with circular economy was small. Sweden’s government needed to act in the question and focus more on top-down instead on today’s down-top work. The municipalities needed to get guidelines and support to make decisions that promoted circular economy since it was an important part of a sustainable development.

    Svenska domstolars analyskriterier av målsägande barns utsagor vid sexualbrott ur utsage- och utvecklingspsykologiskt perspektiv2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Few reported cases of sexual crime against children lead to prosecution. This might depend on the child’s testimony – often the main evidence – which doesn’t satisfy the court’s requirement for evidence. The general capacity of an adult to determine reliability in children’s testimonies is low. In legal usage, testimonies are valued by the use of criteria such as quantity of details, logic and constancy, which may not be adjusted to fit a child and sometimes lacks empirical support. This study examined which criteria the Swedish courts invoke with reliability assessments of the plaintiff’s testimony in sexual crimes against children. One hundred grounds for decisions from 2017 were examined from legal usage (NJA 2010 s 671), testimonial research (SVA’s CBA), and developmental psychological aspects. The results found a focus on general maintained criteria according to practice, while research based criteria, adjusted specifically for the different ages of children who have been victims of sexual crime, were however used to a low degree. The developmental psychological knowledge seems general and to a low degree adjusted to the various developmental stages of children. Finally, it is argued that increased usage of more research based criteria, adjusted to suit children and such child psychological knowledge, could increase the prosecution degree. This would have a positive multiplying effect on crime reporting tendencies, the view of the justice’s legitimacy, and the general degree of justice in society. Lastly, the testimonial guidelines of the Swedish high court are redefined from testimonial research.

    Design and use of 3D typography for indoor Augmented Reality mobile applications2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Augmented Reality (AR), a concept where the real word is being enhanced with computer generated objects and text, has evolved and become a popular tool to communicate information through. Research on how the technique can be optimized regarding the technical aspects has been made, but not regarding how typography in three dimensions should be designed and used in AR applications. Therefore this master’s thesis investigates three different design attributes of typography in three dimensions. The three attributes are: typeface style, color, and weight including depth, and how they affect the visibility of the text in an indoor AR environment. A user study was conducted, both with regular users but also with users that were considered experts in the field of typography and design, to investigate differences of the visibility regarding the typography’s design attributes. The result shows noteworthy differences between two pairs of AR simulations containing different typography among the regular users. This along with a slight favoritism of bright colored text against dark colored text, even though no notable different could be seen regarding color alone. Discussions regarding the design attributes of the typography affect the legibility of the text, and what could have been done differently to achieve an even more conclusive result. To summarize this thesis, the objective resulted in design guidelines regarding typography for indoor mobile AR applications.

    Effekter av nära-nollenergikravet för projektering av flerbostadshus2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In order to steer development towards more energy efficient buildings, the EU parliament have ruled that all buildings produced after the 1st of January 2021 should be classified as near-zero energy houses. This objective is expected to come as stricter energy performance requirements in 2020, and the companies that design the buildings are now facing a change. This study has been made on behalf of Sweco Architects AB in Umeå with the purpose to evaluate what the effects of the EU directive has on one of their designed multi-family houses. Furthermore, the purpose is to give a broader view on what effects the coming energy performance regulations have on other multi-family houses in Umeå. The aim of the report is to obtain a primary energy number, calculated with regard to the forthcoming changes, as well as to study how much a multi-family house’s primary energy number is affected by the forthcoming energy requirements. Furthermore, the aim is to investigate how the primary energy number is affected by the regulations regarding sources heat production of buildings. A reference building is calculated in the energy calculating software BV2 in order to compare energy use and average heat transfer coefficient to the current as well as the future energy performance requirements for near-zero energy houses. After that, studies are made to see how the primary energy number is affected by the changes taking effect 2020. After calculations in BV2 , a primary energy number of 71.7 kWh/m2 per year was established along with an average heat transfer coefficient of 0.288 W/m2K. These pass and fulfill the current as well as the forthcoming requirement levels, and therefore the reference building is well put-up against the regulations that take effect in 2020. Several simulations of a multi-family house with a primary energy number of 85 kWh/m2 per year were calculated on the basis of future values for primary energy factor and geographical adjustment factor. In all cases the primary energy number decreased with about 12 %. As the forthcoming requirement level reduces with about 9 %, it could be concluded that if a multi-family house in Umeå with central heating fulfills the current regulations, it will fulfill the forthcoming ones as well. However, the regulations will be tougher for electricity-heated buildings followed by buildings that obtain their heating from biofuels, gas or oil.

    Assessing the walking access to bus stops in Umeå urban area and the relationship with the socio-economic characteristics2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    To reduce greenhouse gas emissions in the atmosphere and protect the environment, Swedish cities are heavily invested in sustainable development by developing pedestrian roads and intensifying public transport. Their goal is to make the population less dependent on cars by facilitating accessibility to transit transport. The urban area of ​​Umeå (Sweden), which is experiencing an annual increasing of it population due to urban development, includes 244 km of pedestrian or bike routes and an intensified bus network. The purpose of this paper is to evaluate the walking accessibility of the population at bus stops and to analyze the socio-economic relationship. The use of GIS tools allowed to calculate the proportion of the population and the houses around the bus stop, the average distance accessibility. The use of 3D allowed the observation of access constraints related to the topography and to calculate the slope. The use of the multiple regression model has analyzed the relationship between the shortest accessibility distance and the socio-economic factors that are the income, gender and age. The results show that the average distance of access to the bus stop is 186m. 99.2% of the population lives within 800m from the bus stops. The results of the regression showed that income is the main factor that pushes people to take the bus and live in certain types of housing. The observation of the 3d map and the calculation of the slope made it possible to know the neighborhoods established in the hill and whose residents are susceptible to spend more energy than the other inhabitant living on flat ground. The results mean that most people living in the urban area of ​​Umeå have good access to the bus stop whatever the social group, the level of income and the type of housing.

    Att inte bli iakttagen men ändå bli sedd: En studie om tjejers trygghet i det offentliga rummet och hur det kan planeras för trygga och jämställda miljöer2018Independent thesis Basic level (degree of Bachelor), 180 HE creditsStudent thesis
    Abstract [en]

    Abstract

    Making individuals feel safe in public space is an increasingly relevant issue in planning the city's public space. However, fear is not easy to explain or counteract as this is something that is highly subjective. Many urban planning projects are being carried out today focusing on creating safe and equal environments. Such a project is Frizon in Umeå municipality, which is a meeting place based on young girls' experience of security and gender equality.This study tries to create an understanding of how planners can work with girls' safety in the public space, as well as create an understanding of how places that are planned based on security and gender equality can be perceived.The study has been conducted through interviews, surveys and observations, in which young girls experience the city of Umeå and the meeting place Frizon has been the focus.The result shows that the city is primarily a place to hang out with friends and the places most used by the girls in the city are the central parts for shopping and food, but also some of the city's parks.Many of the girls who participated in the study feel insecure sometimes when in the city, but this is something that occurs mainly when they are alone. Hanging out with their friends is not just something they do for socializing, but this is also something that gives them a sense of security. The result also shows that Frizon is an appreciated place by many girls, but that the site partially feels somewhat unavailable during certain times of the day and year.

    Trygghetsuppfattningar och könsnormativa beteenden: Unga mäns ideér och uppfattningar om trygghet på Ålidhem, Umeå2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Abstract

    Feelings of safeness in public space differs a lot between the sexes, where women more often than men feel unsafe. But how do men relate to feelings of safeness in public spaces and how does unsafeness affect the relation between men and women? This study focusses on men’s behaviour towards women and how their behaviour changes during times of unsafeness, and how this behaviour affect´s men´s relationship with their romantic partners. The study is a case study and will focus on the city district Ålidhem in Umeå city, which reputation has suffered from the current image that local medias have projected. This case is interesting when it allows us to study how men in today´s society relate to problems with safeness in public space.

    The study´s result is based in six qualitative semi-structured interviews. the interviews were conducted with six young men in age 20-30 who had experience living in- or had prior experience living in the city district Ålidhem or had a relationship with a woman who had a similar experience. The interviews were later analysed through a narrative analysis method.

    The study´s result show that the men are more open with expressing their feelings of unsafeness and to talk about what types of factors that affect their mindset than previous studies show. These men sometimes felt that they got perceived as threatening elements in public spaces by unknown women, especially at night. This perception of the men as threatening elements sometimes caused the men to change their behaviour, like slowing down or taking other paths to their destination, to dampen the woman´s feeling of anxiety. The men themselves sometimes felt anxiety towards their romantic partner when they move in public spaces and they sometimes applied certain strategies to safeguard them. These strategies however weren’t a product of the men’s anxiety, but rather more often a product of the women´s.

    KEYWORDS: Safety in public space, Gender normative behaviour, Security planning

    Hälsodestinationer i norr som terapeutiska landskap: En fallstudie av Källans spa i Västerbotten2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The search for better quality of life is in our human nature. Health and wellness tourism is therefore not a new phenomenon, but the business is growing in modern day society. Our stressful lives and the need to get away from it is one reason for this change. Traveling to a health destination is one way to increase our wellness state. The purpose of this study is to explore what aspects that effects the well-being of visitors of health destinations in the north. Using the theory of therapeutic landscapes as the theoretical framework, this was done by a case study of Källans spa, which is a spa facility in Västerbotten northern Sweden. People come here to get away from everyday life, relax and recharge in a natural environment.

     

    Data collection was collected through interviews with overnight guests at Källans spa. The material has later been analysed using thematic analysis to find connections with therapeutic landscapes. Results show important aspects for well-being in the physical and social environment while well-being aspects from the spiritual environment appear weak.

    Hur kan de ha tänkt?: En retrospektiv reflektion kring ansvaret för jämställdhet i och under kortfilmsproduktioner2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    There are a many types of digital media productions and in this paper, film is seen as one of them. This study focuses on who can be seen as responsible for their production – the designer for their design, the director for their film. To explore this, the paper uses a qualitative method to first explore a number of short films and then analyze the findings with the use of retrospective reflection. To do this, the paper combines mainly design theory, feminist theory and film theory. The main focus of the paper is to  use retrospective reflection to explore the responsibility of equality in short film productions. The study relies on a template, which has been developed during the process.  Overall, the paper has a focus on equality and whether or not the portrayal of men and women in film change when a woman is directing compared to when a man is. The conclusion of the paper is that the short film industry in Sweden is both more and less equal than the film industry in total, and that retrospective reflection is an effective tool to use in this kind of study.

    Jobbet, hemmet och alla hållplatser däremellan: En kvalitativ undersökning av kvinnors upplevelser av arbetsresor2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Mobility is a term used to describe people's movement in space. The individual's choice of transportation mode has always varied depending on factors such as availability and economy, but also on gender. Studies show that in most cases, the woman in a family travels collectively to work while the man uses the car. Women furthermore tend to seek work closer to home because of the continued perception of themselves as the main accountable for nursing children. Collective modes of transport possess a variety of factors which affects the user's design of everyday life. Timetables, fixed stops and delays are some examples of obstacles that a collective traveler needs to take into account when planning the travel. Furthermore higher stress levels and limited leisure time are examples of consequences that can affect public transport users. The purpose of this qualitative study is to investigate women's experience of work trips and how they deal with possible disturbances in the work travel. The goal is to gain a deeper insight into work trips as part of an individual's daily life. In this case women living in a society located ca 30 km from their workplace in northern Sweden. For this reason, it was considered valuable for the study to conduct in depth interviews. The analysis method underlying this study is a thematic analysis. The analytic coding led to the finding of 3 themes regarding women´s perception about work travel. The themes were; reliability in the transport system, individual flexibility and personal priorities.

    SELF-COMPASSION HOS STUDENTER: KROPPSUPPFATTNING OCH PERFEKTIONISM SOM PREDIKTORER AV SELF-COMPASSION2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The interest of the effect of self-compassion on psychological wellbeing has increased. Self-compassion is negatively associated with self-criticism, anxiety and obsession over and evaluation of the own body. Self-compassion is considered to protect against the negative effects of perfectionism. Since self-compassion is believed to improve mental health, it is important to investigate which variables that predict self-compassion. The aim of this study was to examine if the variables body image and perfectionism predicted self-compassion. The self- report questionnaires Self-compassion Scale Short Form, Frosts´s Multidimensional Perfectionism Scale and Body Shape Questionnaire-8C were administered to the participants. The result was calculated using hierarchical regression analysis. The result demonstrated that the subscale regarding perfectionism, Concern over Mistakes and Doubts about Actions, and sex significantly predicted self-compassion and explained a significant proportion of the variance in self-compassion. Body image did not significantly predict self-compassion and did not explain a significant proportion of the variance in self-compassion. Further research regarding potential concordance between perfectionism and body image is desirable.

    Sedici Alberi: Analisi dei realia culturospecifici nella traduzione di un romanzo norvegese in italiano2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis examines the translation of cultural elements from Norwegian to Italian. The analysis is made on the basis of theories of translation studies and focuses on the realia found in the contemporary Norwegian novel Svøm med dem som drukner, written by Lars Mytting and published by Gyldendal in 2014.

    The initial hypothesis of the work was that in the Italian translation the geographical-cultural aspects would be dominant and the plot and psychological aspects subdominant; that is, a hierarchy of dominants opposite of that of the original in Norwegian.

    The thesis presents the results of analytical parallel reading of the original Svøm med dem som drukner and the Italian version Sedici Alberi from 2017, translated by Alessandro Storti. During the parallel reading words and phrases specific to the Norwegian language culture (realia) were collected and grouped according to the type of realia (geographical, ethnographical or political/social as suggested by Osimo) and the translation strategy used (transcribing, creation of a new word or calque, using a different related word from the source language etc. as suggested by Osimo). While some of the strategies lead to bringing the translation close to the original (adequacy), others make the word or phrase, to a varying extent, consistent with the target culture (acceptability).

    The results obtained confirm the original hypothesis that Sedici Alberi would be an “adequate” translation. Further work in this area could focus on the analysis of style and language in the same translation, to see whether also these aspects conform with the translation being “adequate”.

    Planeringsnivåer och Störutrymme: En studie i övertonshalt och kravställning på lågspänningsnätet2018Independent thesis Advanced level (professional degree), 300 HE creditsStudent thesis
    Abstract [sv]

    Elektricitet blir allt vanligare i hemmet och idag är stora delar av samhället beroende av en avbrottsfri elförsörjning. När transistorn gjorde sitt intåg runt 1950-1960-talet skedde en förändring i de elektriska lasterna på nätet; från att vara mestadels linjära resisistiva laster tillkom flera olinjära laster i form av till exempel radio och TV.Med dessa olinjära laster uppstod problem med elkvaliteten som tidigare inte funnits i större utsträckning.

    Umeå kommun har de senaste åren satsat på helelektriska bussar som en del av en lösning på de problem man haft med buller och dålig luftkvalitet i centrala Umeå. För att driva dessa elbussar används snabbladdare, vilket är en kraftigt olinjär last. I en tidigare studie påvisades att under tider när laddning skedde hos dessa snabbladdare kunde det förekomma höga övertonshalter, där elkvalitetsnormen EIFS 2013:1 emellanåt överskreds.

    Syftet med det här arbetet är att utröna vilka krav Umeå Energi bör ställa vid nya bussladdare och vilka krav som borde ställts vid de första bussladdarna, gällande elkvalitetsstörningar. Målet är att föreslå planeringsnivåer som Umeå Energi kan använda för att ställa krav och fördela störutrymme för kunder. Det finns flera olika modeller för att fördela störutrymme där målet är att föreslå en som passar Umeå Energis nät. Endast planeringsnivåer för övertoner föreslås då övertoner visade störst problematik i den tidigare studien.

    För att bestämma planeringsnivåer gjordes trendanalyser på övertonsdata från fyra nätstationer och fem transformatorer under fyra års tid. Trendlinjer plottades upp med minsta kvadratmetoden och planeringsnivåer bestämdes utifrån hur mycket övertonshalten hade ökat relativt elkvalitetsnormen EIFS 2013:1.

    De planeringsnivåer som föreslogs ligger mellan 85 % till 100 % av de krav som EIFS 2013:1 ställer. Metod för fördelning av störutrymme föreslås följa metoden i ”Fördelning av störutrymme” som publicerades i en energiforskrapport. Slutsatser från det här projektet är att det är svårt att bestämma generella planeringsnivåer på lågspänningsnätet och det saknas metoder som beskriver hur det ska göras. Vidare har det visat sig att de flesta övertoner, upp till 25:e övertonen,ökar på Umeå Energis elnät, på de punkter som undersökts. Framförallt uppvisar den 7:e övertonen en större ökning än de andra.

    Possible competences to be aimed at in ethics education: ethical competences highlighted in educational research journals2018In: Journal of Beliefs and Values, ISSN 1361-7672, E-ISSN 1469-9362, Vol. 39, no 2, p. 195-208Article in journal (Refereed)
    Abstract [en]

    The aim of this article is to present varieties of ethical competence that are highlighted in ethics and moral education research articles, and to discuss them in the light of competences stressed in the Swedish curriculum, understood as an example of ethics education in compulsory school. The material consists of 1,940 educational research articles published between 2000 and 2015, and the method of analysis is inductive, focusing on ethical competence. One finding is the similarity between the study’s tentative formulation of identified ethical competences in four categories, and Rest’s understanding of acting morally, captured in the four components: sensitivity, judgement, motivation and implementation. Based on the analysis of the articles, broader understandings of these focuses are developed, and later discussed in relation to Swedish ethics education, characterised as both a conservative and liberal values education. The analyses and comparison show the importance of the components of moral sensitivity and moral implementation and their relative absence in the Swedish curriculum, but also how moral judgement must include a competence to evaluate moral motivations, where empirically testable reasons are also central. Moreover, the risk of neglecting contextual, situational and knowledge-related aspects of ethical competence is highlighted.

    Ökad matarvattentemperatur vid biopannan Smurfit Kappa Piteå: Increased feedwater temperature at biomass boiler Smurfit Kappa Piteå2018Independent thesis Advanced level (professional degree), 300 HE creditsStudent thesis
    Abstract [en]

    Smurfit Kappa Piteå is the largest kraftliner producer in Europe. At the mill they have five different steam producers and one of those is the biomass boiler, which is a steam boiler producing overheated steam at 120 bar and 520C. The purpose of this report is to investigate the possibilities to increase the feedwater temperature from today’s 180C to 210C. The consequences on the system are depending on the temperature in the different process stages and the process temperatures are therefore calculated via a method named The NTU-method which is a suitable method to analyze the heat transfer within an object when the ingoing and outgoing temperature are unknown. The feedwater is preheated with a heat exchanger that is heating the feedwater from 130C to 180C using steam with a pressure of 11 Bar. To increase the temperature to the desired  the approach is to install a complementary feedwater heater that uses steam with a pressure of 27 Bar. The new heater is supposed to heat the feedwater from 180C to 210C while the old heater takes the temperature from 130C to 180C. If the old heat exchanger approaches its end of life span it may have to be replaced with a new one with the same design data. One way to fulfill the required heating is to install one feedwater heater that takes the temperature from 130C to 180C using steam with a pressure of 11 Bar and in the next step install the second feedwater heater that takes the temperature from 180C to 210C using steam with a pressure of 27 Bar. There are two alternatives to installation of complementing high pressure heat exchanger. First alternative A is to install the second feedwater heat exchanger between the economizer and the steam dome. Second alternative B is to install the second feedwater heat exchanger between the already existent heat exchanger and the economizer. The consequence of the installation B is an increased energy loss due to the combustion gases while the consequence of installation A does not involve any increase in energy losses. Therefore, alternative A is wiser. However, whatever alternative that is chosen problem will arise since the temperature margin between the steam dome’s saturation temperature and incoming feedwater temperature needs to be at least 25C. This means that the largest possible pre-warming between the boiler’s workload 50-110% is 21C which not do apply to the whole interval. So, as it seems, the utilization of a second feedwater heat exchanger is not applicable over the whole interval of workloads. The increased feedwater temperature come with other consequences on the system. The whole system will be changed due to the increased temperature and it will affect the details. Some of the pipes must be replaced with new ones that fulfills the restrictions accompanying higher process temperatures. The purpose of the increased feedwater temperature is to increase the mass flow steam to the turbine. From calculations and the extraction-steam-consumption graph the increasing net power outcome from the turbine will increase with about 7.5% due to the increasing feedwater temperature. This will make the turbine produce even more electric energy and generate a bigger income to the factory. The investment cost is in total approximately 25MSEK, including replacing the old feedwater heater with a new one and installing a second feedwater heater. With a payback time of eight years and a life span of ten years it is necessary to question the economic potential of the installation. It provides a hint of the potential of the project. However, one should know that all numbers in this report are estimated from rough calculations.

    Bildning och sulfatering av fluorider i aska vid förbränning2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Combustion of waste in combined heat- and power plants are the primary solution for waste that is not recycled or reused in Sweden today. Municipal solid waste contains a wide range of ash-forming elements, which could lead to operational problems in the boiler that limits the plant’s efficiency. Different elements are found in different waste fractions, and some can cause severe corrosion problems in heat transferring parts of the boiler. The heat and power industry has been aware of the problems associated with chlorine for a long time, as this is an element that is known to contribute to corrosion. New materials mean that high levels of previously unknown elements for the heat and power industry enters the plants. One of these elements is fluorine which is found in fluoropolymers which are chemically inert plastics. Fluoropolymers are found in sports and outdoor clothing, as well as cookware and a number of other products, and the production of these type of materials is expected to increase significantly over the next few years.

     

    The purpose of this work was to investigate the distribution of fluorine by addition of sodium fluoride (NaF) to pure wood pellets. This was done through thermodynamic calculations and bench scale combustion tests. Four fuel mixtures were tested, one containing NaF alone, one containing sodium chloride (NaCl), one containing both NaF and NaCl and one containing NaF, NaCl and sulfur. During combustion tests, the concentrations of HCl, HF and SO2 in the flue gases were logged. Analysis of bottom ash, deposits and particles in the flue gas was performed with SEM/EDS and XRD-analysis after each combustion test. The results showed that fluorine appears to be more likely than chlorine to stay in the bottom ash. This was confirmed by thermodynamic equilibrium calculations and by combustion tests. Furthermore, the thermodynamic equilibrium calculations showed that a large share of fluorine should end up in the flue gas as HF. Furthermore, the combustion tests showed that sulfation of fluorine salts occurs at lower levels of sulfur than sulfation of chlorine salts. In practice, this means that if the levels of fluorine-rich fuel increases in a waste incineration plant, the proportion of HF in the flue gases should increase and that some of the sulfur in the fuel mixture will be used for sulfation of fluorine salts if they are formed. The distribution of fluorine if fluorinated plastics are added to the fuel is not investigated in this work and something that should be investigated in the future.

    Friluftslivets möjligheter och hinder: En kvalitativ undersökning av idrottslärares uppfattningar av friluftslivsundervisning2018Independent thesis Advanced level (professional degree), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [sv]

    Uppsatsen söker svar hur svenska idrottslärare arbetar med friluftsliv, ett område som pedagoger kan uppleva som problematiskt. Friluftsliv är något som kan bidra till såväl fysisk som psykiskt välmående för individer som genomför friluftslivsaktiviteter. Hur undervisningen ska bedrivas bestäms utifrån skolan styrdokument men den enskilda idrottsläraren får tolka styrdokumenten vilket resulterar i att undervisningen ser olika ut beroende på vilka tolkningar idrottsläraren gör. För att ta del av idrottslärares uppfattningar genomfördes e-postintervjuer som sedan tolkades med hjälp av den hermeneutiska analysmetoden. Resultatet påvisar att uppsatsens deltagare inte är överens om styrdokumenten behöver preciseras eller ej. Informanterna belyser att tid är en faktor som påverkar momentet i stor utsträckning. Uppsatsen påvisar att idrottslärare genomför friluftsliv praktiskt något som är positivt då eleverna då får möjligheter att ta del av de positiva effekterna friluftsliv kan leda till.

    Kan någon svara, bebygga eller bevara?: En studie om Piteå kommuns förhållning till jordbruksmarkens värde2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In a time where many municipalities have an ambition to increase their population, new buildings have to be established at the same time the future value of agricultural land has increased largely the last few decades. This can create dividing lines where the value of farmland stands against new construction. In the 1970s much settlements were added to agricultural land in the municipality of Piteå. At this point there were no clear regulations of the land use resource value. In the current situation the municipality wants to densify the settlement and this creates problems as the law says that usable agricultural land can’t be established if it doesn’t satisfy an essential social interest. In this study, the municipality of Piteå and Länsstyrelsen Norrbotten’s relation to the conservation of agricultural land has been investigated to find out if there is any differences and if so in what way that is expressed.

    Influence of sea ice seeding on the spring phytoplankton bloom: An experimental study in the Gulf of Bothnia2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The influence of sea ice seeding on the northern Baltic Sea´s pelagic phytoplankton spring bloom was studied in a laboratory experiment in which microcosms mimicked sea conditions. On March 26th, 2018, samples (ice cores and seawater) were taken from land-fast ice at a coastal station in the Gulf of Bothnia. The seeding experiment lasted for 9 days, during which a 12:12 hours light:dark incubation took place. Four different treatments (two with ice and two without it) were set up in twelve incubated microcosms. Samples for analyses were taken on days 0, 3, 6 and 9. On day 0, measurements were carried out on four melted ice cores and on seawater. On the remaining days analyses were performed on the incubated microcosms. The measured variables were: chlorophyll a, phytoplankton abundance, bacterial abundance, conductivity and nutrients (TDN and TDP). The most abundant algal species were identified in a qualitative analysis. The obtained data were processed to calculate the average and standard deviations and to assess the existence of statistically significant differences among the treatments. A significant increase in chlorophyll a, phytoplankton and heterotrophic bacteria abundances was detected. A parallel decline in the nutrient concentrations was observed. A relationship between phytoplankton´s degree of influence and cell-size is suggested: cells > 3µm were more abundant in ice than in seawater, and the opposite tendency was appreciated for cells < 3 µm. My study shows that sea ice seeding can have a marked seeding effect on the size structure of the spring phytoplankton bloom.

    Marknadsföring av en destination efter en kris: Tunisien efter terrorattackerna 20152018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study aims to reveal what marketing strategies Tunisia has used to alter their place image for the better after the terror attacks that occurred in the country 2015. These terror attacks had a negative effect on Tunisia’s tourism industry; the annual GDP brought by the tourist industry decreased by 19,73%. By using “the multi-step model for altering place image” developed by Eli Avraham and Eran Ketter, this study contains a thematic analysis on qualitative content such as news reports, advertising campaigns and press interviews to uncover what marketing strategies were used by Tunisian official tourism marketers and officials to restore the destinations positive place image and bring back tourist after the terror attacks. The result shows that Tunisia has used strategies from all three categories of strategies; source, audience and message. Furthermore, this study contributes to a better understanding on what marketing strategies a destination could use to alter their place image after gone through a crisis.

    Abstract [en]

    This study seeks to examine whether a relation can be found between the number of shoreline exemptions and the development of Umeå municipalities population, or not. The weight of this paper will be focusing on the importance of place attractiveness and social place identity for people’s desires and ambitions to live near a lake or the coast. The policies of planning will also be highlighted in order to receive greater understanding of why people apply for shoreline exemptions. Four semi- structured interviews with planners from Umeå municipality were therefor held with the ambition to complement the quantitative findings of the development of exemptions.

    The presenting results indicates that an increase of shoreline exemptions can be stated as well as the actions within the exemptions. The population has steadily increased trough out the studied years, 2014-2017. The relation between these findings can be argued have had a similar development, but we cannot be sure to say that they solely affect each other. Therefor the findings will be explained by earlier research regarding residential preferences, the desire to live with water view and planning policies that responds to these factors.

    Dimensionering av limträstomme till Coop butik: med en miljöjämförelse mellan stommaterialen stål och limträ2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The construction process in Sweden generates ten million carbon dioxide equivalents per year. Actors involved in the construction industry needs to clarify the climate load of the construction process and increase the knowledge of it. In this paper an alternative frame in glulam has been designed for a grocery store with a steel frame. As the bearing beam has a tensed three joint truss been used with a range of 40 meter. This work also includes an environmental comparison between steel and glulam as frame material set out from the amount of steel and glulam used in the frames, 31 ton of steel compared with 150 m3 glulam. The environmental analyses have been done by using the Eco strategy wheel, that is a tool used for optimizing a product regarding the environment, and by identifying environmental aspects from the manufacturing of the materials. The environmental aspects were then associated with the sustainability principles and graded by extent, severity and frequency. The ambition of this project was to show that a glulam frame can carry loads as good as a steel frame and to increase the knowledge of persons involved in the construction process to choose materials that are good for the environment. The results show that it was possible to design a glulam frame for the store but with an increased building height and volume as a consequence. Both frames could carry the loads but had different qualities. When the use of energy in the manufacture process were compared it showed that the glulam frame used almost twice the amount of energy compared to the steel frame, but in the process of manufacturing glulam almost all energy used came from renewable sources while the manufacturing of steel uses almost only energy from non-renewable sources. The carbon dioxide emission of the steel frame was 170 ton more than of the glulam frame that instead binds carbon dioxide. In the production of the steel frame the steel consumes 600 m3 more fresh water than the glulam frame and the steel process generate more waste. The transport of the steel frame also generates more carbon dioxide than the transport of the glulam, much thanks to the nearness of material and supplier of glulam to the construction site. This shows that it is good for the environment to think local.

    Dimensionering av stålstomme och brandskyddsfärg vid en given brandteknisk klass2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    WSP Structures in Umeå wants the student to propose a preliminary design for a steel frame with a given input, considering the ultimate limit state and fire. The project has been limited to design the frame for the ultimate limit state and the fire design has been limited to calculate the amount of fire retardant paint needed for fire classification R30 for building components. The frame is delimited to columns, beams, horizontal stabilization and connecting joints between parts. With the help of theory, the resistance and the design amount of fire protection are verified, of which the results are verified.

     

    As a solution, a model is created in the modeling software FEM-Design where load combinations are created by the given input and assumptions. Using the software´s design tool, the needed sections for columns and beams is calculated. Load effects that accords at joints is indicated by the program and is used to design joints and connections between parts according to SBI:s publications for beam-column connections and column footings. Most utilized elements were the “middle column”, which were designed to a HEA 200 profile with an 80% utilization. Detailed results are presented with tables which presents the utilization for each element. Designed columns, beams and joints can be found in level, section and detail drawings.

     

    With the help of the created FEM model and used theory about fire design, the amount of fire retardant paint is calculated with the accidental load combination. The accidental load combination generates a lower utilization, which is used to calculate the needed amount of paint based on the manufacturer´s table. Columns received an amount of 750 g/m2 and beams received an amount of 1000 g/m2. Horizontal stabilizing elements didn´t receive any protection because it could be shown that columns could be calculated with a fixed support during the accidental load combination with a significant lower horizontal load.

     

    The student thesis emphasizes the importance of finding a balance between the amount of paint and section and embracing a discussion about fire protection for joints. The utility rate for columns and beams became a guideline for the utility for joints since the amount of paint applied on the beam and connecting joints is the same, it would be a problem for example if the joint is utilized more than the connected beam. Also, determining the amount of paint needed is difficult if different steel grades are used in a joint and if details such as stiffeners are narrower than the thickness of the connecting column/beam.

    THE PROSPECT OF LIVING FILTERS: Reducing building sector energy demands by improving indoor air quality2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Today people spend all the more time indoors. Asthma, allergies and Sick Building Syndrome (SBS) are affecting an increasing number of people. The remedy for all these affections has long been to increase the volume flow of outdoor air in the ventilation but at the same time cities all over the world are struggling with air pollution and smog rising above endangering levels. Living filters present a new solution where part of the indoor air can be purified and recirculated in a building. This project has compiled research on the area to describe the how and why concerning air purification by plants. Independent research conclude that plants can reduce most hazardous chemical agents in the air.

    Climate change, global warming and increasing demands on energy performance induces a race for countries and companies to improve energy efficiency in all sectors. To the building engineering sector living filters presents a unique solution to cut ventilation energy loses. A powerful simulation tool IDA ICE was used to estimate the energy saving capacity when a living filter is applied in the lunch room of an office floor. Another simulation software; Comsol Multiphysics was used to illustrate the aspects of ventilation flow when a living filter cabinet is deployed in a room. The simulation results show that for three living filter cabinets each measuring 0,7x0,8x1,73 cm the buildings energy usage is reduced with more than the living filters use to operate. The single room simulations then show how a living filter can be accommodated with both mixing and displacing ventilation. However, these simulations also illustrate the importance of the living filters placement to achieve maximum ventilation efficiency. 

    The conclusions from this work are that living filters can reduce building sector energy demands and provide significant indoor environmental benefits. The main issue for using living filters is identified to be building regulations putting strict demands on outdoor air flow and that the hygienic function of each living filter must be verified before it may replace outdoor air.

    Cultura imperial y conciencia etnocentrista en la obra Marianela de Pérez Galdós2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The following thesis studies the imperialist expressions present in the novel “Marianela” by Benito Pérez Galdós. These expressions may point to attitudes and ideological stands of the Spanish society of the time. Through analysis of the imperialist discourse in the novel, this investigation reveals vestiges of the origins of the representation of otherness and the configuration of the other as the peripheral, as a referent of otherness merged with the imperialist discourse of the time. It also reveals traits that may point to the colonialist character such as the ambition of the appropriation of the potentiality of the workforce and the epistemic violence found in the analysis of the novel’s dialogues. This study concludes that, within the discourse of the focusing character, Golfín, an ideal of subjectivity is revealed. This ideal points to the one characterised by the stereotype of the new bourgeois subject, who brings Modernity with him. At the same time, the discourse is influenced by the constructs of subjectivity drawn from the ideals of conquest, the Eurocentrism and the classification of the human being according to its adaptation, or lack of, to the bourgeois ideal.

    Slutrapport från AKTIKON-PROJEKTET i Örnsköldsviks kommun: Arbetsmiljö, fysisk aktivitet, hälsa och produktivitet i aktivitetsbaserad kontorsmiljö – en kontrollerad studie i Örnsköldsviks kommun2018Report (Other academic)
    Abstract [sv]

    Projektet Aktivitetsbaserat Kontor (AktiKon) har följt och utvärderat en förändringsprocess i Örnsköldsviks kommun där tjänstemännen i kommunen flyttade från cellkontor till antingen ett aktivitetsbaserat kontor (AB-kontor) eller ett cellkontor. Syftet med forskningsprojektet var att studera effekter på arbetsmiljö, fysisk aktivitet, hälsa och produktivitet i aktivitetsbaserad kontorsmiljö och kunna jämföra med fortsatt arbete i cellkontor. Mätningar med enkäter, fokusgruppsintervjuer, gåturer och observationer utfördes 6 mån före flytt och 6 respektive 18 månader efter flytt. Individuella intervjuer av personer med upplevd funktionsnedsättning utfördes ca 10 månader efter flytt. Rörelsemätningar utfördes vid fem olika tillfällen under flyttprocessen.

    I denna rapport har vi valt att redovisa enkätresultat från anställda som vi har kunnat följa över tid, d.v.s. individer där vi har resultat från enkät besvarad före flytt och från minst ett tillfälle efter flytt. Den ursprungliga studiepopulationen som studerades med denna metod bestod från början av 374 anställda och vid den sista uppföljningen, 18 månader efter flytt, av 152 anställda i AB-kontoret och 63 i cellkontoret. De två grupperna som flyttade till olika kontorsmiljöer var inte helt jämförbara. Exempelvis var det fler män och chefer som flyttade till AB-kontoret och yrkesgrupperna var inte heller lika, men alla som ingick i projektet var tjänstemän inom samma kommun.

    De som flyttade till AB-kontoret upplevde den nya kontorsmiljön som estetiskt tilltalande och luftkvaliteten god. De som flyttade till nya cellkontor hade utifrån kvalitativa intervjuer inte en lika positiv uppfattning vad gäller kontorets design och inredning.

    Arbetsbelastningen och olika typer av krav såg lika ut över tid för respektive grupp. Det var vid 18 månader efter flytt ingen skillnad jämfört med före flytt i hälsofrämjande arbetsfaktorer undersökta med WEMS-instrumentet (Work Experience Measurement Scale) för de som flyttat till AB-kontor. Det var inte heller någon skillnad över tid i jämförelse med de som flyttat till cellkontor. Datorstödet upplevdes mycket positivt av de som flyttade till AB-kontoret och de blev något mer nöjda än de som flyttade till cellkontor. Det fanns i AB-kontoret inte någon säker skillnad i upplevelse av samarbete mellan olika arbetsgrupper eller inom hela organisationen vid 18 månader efter flytt jämfört med utgångsläget och inte heller någon säker skillnad över tid jämfört med cellkontoret. De som flyttade till AB-kontor rapporterade efter flytten en ökad störning av ljud och besvär av bristande avskildhet. Man upplevde i genomsnitt en lägre produktivitet i AB-kontoret efter flytt och det fanns en skillnad mellan de två kontorstyperna över tid.

    Cheferna var generellt nöjda med att arbeta i AB-kontor och de upplevde inte någon minskad produktivitet vid övergång till AB-kontor. I genomsnitt blev det emellertid en minskad nöjdhet med kontorets utformning i gruppen som flyttade till AB-kontor. Nöjdheten med AB-kontoret varierade beroende på yrke och typ av arbetsuppgifter. De som hade mycket enskilt och koncentrationskrävande datorarbete upplevde mindre nöjdhet efter flytt och angav att de helst ville arbeta i cellkontor om de fick välja. De som arbetade mycket i grupp, behövde vara idérika och ofta diskuterade med kollegor föredrog att arbeta i AB-kontor. Bland dem som helst ville arbeta i cellkontor fanns det en ökad förekomst av problem med stress, långvarig utmattning och psykiska besvär.

    Det framkom ökade problem med koncentrationen hos de som flyttade till AB-kontor. Det fanns däremot inga säkra skillnader över tid mellan grupperna vad gäller skattning av allmän hälsa och förekomst av andra typer av besvär.

    Redan före flytten hade båda grupperna tillgång till höj- och sänkbara bord och det var vanligt att arbeta stående under en rätt stor del av arbetsdagen. Efter flytten ökade tiden i gående och antal steg något i AB-kontoret jämfört med cellkontoret. I AB-kontoret fanns tillgång till gå-band, men dessa användes endast av ett fåtal anställda. Den centralt belägna öppna trappan var omtyckt och användes mycket.

    Sammanfattningsvis visar studien att nöjdhet, preferens och produktivitet i AB-kontor varierar mycket beroende på vilka arbetsuppgifter man har. AB-kontoret fungerar särskilt bra för personer med ledningsuppdrag. För att AB-kontoret ska kunna fungera bra även för personer med funktionsnedsättning måste det finnas system för att fånga upp individuella problem och möjliggöra anpassningar vid behov. Detta gäller särskilt vid psykiska besvär och kognitiva svårigheter. Det är angeläget att det i AB-kontoret finns tillgång till stödytor och resurser i tillräcklig omfattning för alla de olika arbetsuppgifter som ska utföras.

    En viktig erfarenhet i projektet är betydelsen av att kunna beskriva den kontext som förändringen sker i. Genom att göra en processutvärdering har det funnits möjlighet att på ett adekvat sätt tolka och förstå de effekter som framkom vid övergång till AB-kontor.

    Framgångsfaktorer vid övergång till AB-kontor är noggrann kartläggning och analys före flytt, samverkan, delaktighet, överenskomna regler och förhållningssätt, och övergripande rutiner som inkluderar hela kontoret för det fortsatta arbetsmiljöarbetet.

    Evaluation of Convection Suppressor for Concentrating Solar Collectors with a Parabolic Trough2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Absolicon Solar Collector AB in Härnösand, Sweden, develops concentrating solar collectors with a parabolic trough. In the solar collector trough, there is thermal loss due to convection. A convection suppressor was made and used as a method to reduce thermal loss due to convection in the trough. The objective of the project was to evaluate the convection suppressor for solar collectors with a parabolic trough and its impact on the performance (thermal loss characteristics) in two different orientations of the trough, horizontal and inclined. The performance of the solar collector was first measured without the convection suppressor; these results were compared to two previous quasi-dynamical tests of the solar collector performance made by two different institutes, Research Institute of Sweden and SPF Institut für Solartechnik (Switzerland). The comparison was made to validate the test results from the tests without the convection suppressor, which matched. Secondly, when the convection suppressor was made and tested in the two different orientations, the results of the performance with and without the convection suppressor was evaluated as well as the convection suppressor itself. The results showed a significant improvement of the solar collector performance in the aspect of reduced thermal loss when the convection suppressor was used, hence higher efficiency.

    Abstract [en]

    The world is shrinking with the help of different available travel options. But does it shrink our daily routine? What does location of travel nodes such as bus station or train station, giving for consequences in people’s daily life? And where are function of the society in relation to this travel stations?

    This study aims to analyze and investigate railway stations in a specific part of the northern Sweden. The research questions are to investigate their function and relation to the society and people in the area. And, to investigate if there are any correlation between where people live and where functions in the society are placed.

    The study has been performed with qualitative analyzes of the railway station in question and a quantitative approach for the correlation of people and function in the society. The presented data in the thesis has been collected from Statistics Sweden and analyzed in computer program.

    Analyses of the railway stations has showed that they are planed and built to gathering more than one way of traveling. They have been constructed to work for both busses, bicycle, train, cars and pedestrians. Analysis of people and function in the society has showed that there are some geographical relations between them.

    Förbättrad byggarbetsmiljösamordning: Arbetsmiljöarbetet under planering- och projekteringsskedet2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this degree project is to highlight the important work done by the planning and design coordinator for the construction environment in the early stages, and the significance of this for improving the working environment throughout the project. This work will be conveyed to the construction and installation work coordinator, whose task is to build on the work that has begun. At this stage of a project, an important transfer between the two building environment coordination roles takes place. In order for these two roles to be able to be successful, both require education, skills and experience for the upcoming project.

     

    In this project, the planning and design coordinator for the construction environment duties and responsibilities have been studied. Through a literature study, relevant improvement areas could be identified and analyzed. The results of the literature study showed that it is important that the planning and design coordinator has the relevant education, skills and experience to make the biggest impact on the work environment. The work carried out by the planning and design coordinator has to be clear and structured. The handover between the different coordinators is extremely important so that this work is not obstructed. As no guidelines for the handover are given in the literature (2018), a questionnaire with subsequent deep interviews was created. This will produce an indication of improvement areas in the handover process. A total of 12 planning and design coordinator for the construction environment and 6 construction and installation work coordinator participated in interviews and through surveys.

     

    The study has resulted in a plan for the creation of a law list and a checklist of the construction duties for the planning and design coordinator. This checklist makes it easier for the coordinator to perform all their tasks and helps to clarify and structure responsibilities. The study also shows that the transfer between the planning and design coordinator and the construction and installation work coordinator is extremely important. The transfer should be done primarily via a physical meeting with the right documentation as a basis and subsequent meetings via telephone and/or Skype meetings. It is also important that responsibility for the occupational health and safety plan is handed over like a baton in a relay race, and that this process is defined in advance.

     

    A more in-depth study is required for a full analysis regarding the impact of the education, skills and experience of the coordinator. The study shows that there are interesting differences in the assessment and control of construction work coordinator qualifications.

    Teaching in an age of complexity: exploring academic change and development in higher education academia2018Conference paper (Refereed)
    Abstract [en]

    Higher education (HE) has expanded and diversified at an unprecedented rate over the last two decades in response to a rapidly changing educational and political climate (Henkel, 2016; Saroyan and Trigwell, 2015). Change is omnipresent, a constant part of teachers’ sociocultural and organisational practice at multiple levels; at the micro-level of the individual, the meso-level of the department or programme and the mac-ro-level of the institution (Leibowitz et al, 2014; Hannah and Lester, 2009). This suggests that when researching teaching and learning practices it is essential to adopt a holistic perspec-tive, exploring not only individual factors but also sociocultural and structural factors and their interrelationships.

    The research presented is a series of five studies that con-stitute an exploration of academic change and development in a HE teaching and learning environment supported by educational technology. A twelve-year longitudinal study of teachers on an online pharmacy programme forms the basis for the research. The principal aim of the research was to gain a deeper understanding of the factors that influence academic change with the additional aim of providing insight into factors that may be relevant in the design of academic development activities to support teachers and managers in the enhance-ment of teaching and learning. A multilevel approach was used to investigate academic change and development addressing micro-, meso- and macro-levels of the university teaching en-vironment (Hannah and Lester, 2009; Kozlowski and Klein, 2000). The approach captures the influence of factors such as conceptions and approaches to teaching at the micro-lev-el of the individual teacher (Postareff and Lindblom-Ylänne, 2008; Trigwell, Prosser, Martin, & Ramsden, 2005), as well as the influence of systemic factors such as sociocultural and structural context at both the meso-level of the department or programme (Neumann, Parry, & Becher, 2010; Trowler, Saun-ders, & Bamber, 2012) and the macro-level of the institution (Fanghanel, 2007; Leibowitz, et al., 2014).

    The research studies suggest that at micro-level a critical fac-tor in the choice and use of educational technology is the un-derlying conception of and approach to teaching and learning of the teacher (Kim et al, 2013; Glassett, 2009). Opportunities for change and development were found to be facilitated by the sociocultural context of the teacher at meso-level encom-passing support from the community and mediating tools for communication (Mårtensson and Roxå, 2016; Trowler and Wareham, 2008). However institutional policy and strategy at macro-level, as interpreted by the department, was seen to impede change and development, where research is given pri-ority over teaching (Deem and Lucas, 2007; Fanghanel, 2007). At the meso-level of the programme, the opportunity to work together as a team to collaboratively construct and develop practice was found to be of significance in the development of agency and interdisciplinary cooperation (Haapasaari, Eng-eström, & Kerosuo, 2016).

    Taking into account a combined analysis of the five studies, it becomes apparent that change and development in HE is influenced by factors at the micro-level of the individual teacher, by contextual sociocultural factors at the meso-level of the department or programme and by contextual structural factors at the macro-level of the institution. If a deeper under-standing is to be achieved, it is necessary to adopt a holistic approach, considering factors at micro-, meso- and macro-level and the interrelationships between these factors. The research suggests that an effective strategy for the facilitation of aca-demic change and development may be the introduction of a Scholarship of teaching and Learning (SoTL) model where initiatives at the three levels are aligned so that SoTL is linked both to academic development at micro- and meso-levels and excellence and promotional frameworks at macro-level (Booth and Woollacott, 2017).

    Investigating an electroplating method of Co-Cr alloys: A design of experiment approach to determine the impact of key factors on the electroplating process2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Solar energy is increasingly being considered a promising solution to reduce the emissions of CO2 and green house gas. The performance of solar collectors largely depends on the ability to absorb incoming solar radiation with minimal thermal radiation losses. To weigh the potential absorbed energy to thermal losses, the performance criterion (PC) can be used, calculated as PC =α−xε, where α is absorptance, ε is emittance and x is a scaling factor < 1. It has been shown by G. Vargas et al. that Co-Cr alloys excibit great potential (α = 0.98 and ε = 0.03) for use in solar concentrators. The main goal of this project is to quantify the impact of key factors (controlled input variables) on an electroplating process of Co-Cr alloys, using the design of experiment (DOE) methodology. It is part of an ongoing collaboration between Absolicon and the physics department at Umeå university. Six factors were investigated using a fractional factorial (FrF) design. Data was collected through a series of experiments where stainless steel substrates were electroplated with Co-Cr alloys. The resulting samples were analyzed in terms of α and ε as well as the quality of deposition (QD). Using the experimental results, three models were made in a DOE-software called MODDE. Models are used to correlate the factors with each response, i.e. α, ε and QD. Ideally the predictive power of the models (Q2) should be as high as possible, and at least > 0.5. The analysis of variance (ANOVA) test was used to determine the significance of the models. Based on the models, the ’Optimizer’ tool in MODDE was used to predict two set of optimum factor settings, producing two samples, S1 and S2. S1 and S2 were evaluated in terms of α, ε and Qas well as chemical composition and structural properties of the coatings. The predictive power of the models was 0.49 for α, 0.38 for ε and 0.53 for QD. The predictive power of the models were therefore limited. ANOVA-test showed that the models for α and Qwere statistically significant. For all three responses the significant effects were mostly two factor interactions. All three models showed significant lack of fit (model error) as a result of high reproducibility. S1 had the best PCAbsolicon (performance criterion for Absolicons solar collectors) of all samples with 0.858. S2 was not as good, even though it was predicted to have a higher value of PCAbsolicon by MODDE. EDS, XPS and SEM measurements of samples S1 and S2 showed that the two samples were very similar in terms of chemical composition. The main difference was that the coating of S1 was more porous, and also thicker than S2, 0.81 μm compared to 0.26 μm. Even though the models showed some predictive capabilities, the impact of the factors could not be fully determined. That is due to the nature of the FrF-design, which cannot accurately determine two-factor interactions.

    Klassläraren och den nyanlända eleven: En studie om hur klasslärare arbetar med nyanlända elever som direktplacerats i ordinarie klass2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    I dagens skola direktplaceras nyanlända elever i yngre åldrar oftast i ordinarie klass. Många klasslärare ställs därmed inför uppgiften att undervisa elever som inte har grundläggande kunskaper i svenska. Syftet med denna studie är därför att öka kunskapen om hur klasslärare i årskurs 1–2 arbetar med nyanlända elever som direktplacerats i ordinarie klass. Genom att observera lärare i undervisningssituationer och intervjua dem efteråt har slutsatser om lärarnas arbetsmetoder dragits. Även den stöttning och kognitiva utmaning som nyanlända elever får har undersökts. Resultatet visar att lärarna använde varierade arbetsmetoder men att enskilt arbete dominerade i undervisningen. Stöd gavs i form av bilder, demonstrationer, digital teknik, studiehandledare och förstaspråket. Aktiviteterna som eleverna deltog i innebar ibland hög kognitiv utmaning men oftast arbetade eleverna för att träna upp sina färdigheter inom läsning, skrivning och räkning.

    Läsundervisning?: En kvalitativ studie om lärares arbetssätt vid läsinlärning i årskurs 12018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Syftet med studien var att fördjupa kunskapen om läsundervisning i årskurs 1 och därmed undersöka hur lärare beskrev att de arbetade med läsinlärning, både i helklass och för elever med lässvårigheter. I bakgrunden ges en tillbakablick på läsinlärning i ett historiskt perspektiv vidare presenteras viktiga begrepp som rör läsundervisningen. Den teoretiska utgångspunkten i studien bygger på den syntetiska och den analytiska principen. Data som samlas genom kvalitativa intervjuer analyseras genom ett analysverktyg som grundar sig i teorin. Resultatet visade att lärarna tenderade att arbeta syntetiskt i helklass, dock hade de flesta även analytiska inslag i sin läsundervisning. Helklassundervisningen benämns därför som balanserad. De elever som hade lässvårigheter undervisades huvudsakligen syntetiskt, med några undantagsfall där läraren även arbetade analytiskt. Arbetet som berör elever med lässvårigheter bedöms därför i huvudsak vara syntetiskt.

    Lärares användning av målspråket i den engelska undervisningen för åk 1-32018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Studien syftar till att bidra med kunskap om hur lärare använder målspråket i engelskundervisningen, detta görs genom att undersöka lärarnas förhållningssätt till målspråksanvändning samt i vilken utsträckning och på vilket sätt de kommunicerar på målspråket i undervisningen. Med utgångspunkt i teorier och forskning kring språkinlärning och målspråksundervisning har en kvalitativ studie genomförts med hjälp av en intervju och två observationer med respektive lärare. Informanterna bestod av tre lärare som undervisar i engelska inom årskurs 1-3. Resultaten visar att samtliga lärare har en positiv inställning till målspråksanvändning och använde mer engelska än svenska under observationer. Lärarna uttrycker att de vill använda målspråket mer än de gör idag men upplever sig hindrade av ramfaktorer. Slutsatsen är att en positiv inställning troligtvis leder till att läraren använder sig mer av målspråket i undervisningen, men att det inte är realistiskt att förvänta sig att all kommunikation ska kunna ske uteslutande på målspråket.

    Starkare tillsammans?: En fenomenografisk studie om grundlärares uppfattningar och erfarenheter av grupparbete i matematikämnet2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Från att lärare i Sverige haft en negativ uppfattning av grupparbete, har det på senare år skett en ökad användning av arbetsformen i exempelvis matematikämnet. Lärares uppfattningar kan ha påverkan på grupparbetes process och resultat, trots det är forskningsfältet kring detta begränsat. Studien görs utifrån ett fenomenografiskt perspektiv med syfte att öka kunskapen om lärares uppfattningar och erfarenheter av grupparbete i matematikämnet. Frågeställningarna berör lärarnas definition av grupparbete, vad de ser för möjligheter och svårigheter, samt vad de anser är syftet med arbetsformen i matematikämnet. Kvalitativa intervjuer användes vid datainsamling. Resultatet visade att majoriteten av lärarna definierade grupparbete som att två eller fler elever samarbetar med en arbetsuppgift. Lärarnas uttalanden indikerade att de hade en överlag positiv uppfattning av grupparbete, trots att några av lärarna problematiserade arbetsformen. Den positiva uppfattningen grundade sig främst på positiva erfarenheter, såsom att eleverna fick möjlighet att fördjupa matematisk kunskap. Matematiklyftet framkom även som en faktor som påverkat lärarnas uppfattningar. Vidare ansåg flest av lärarna att huvudsyftet med grupparbete var att låta eleverna kommunicera matematik. De lärare som problematiserade arbetsformen utgick från negativa erfarenheter, där svårigheter vid gruppsammansättning och bedömning framstod som några faktorer som påverkat lärarnas uppfattningar av arbetsformen.

    "När man inser att man ska lära någon ett språk från grunden, alltså var börjar man?"2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Studien riktar sig till undervisning i årskurserna 1-3. Syftet med studien är att få mer kunskap om lärares didaktiska verktyg som används för att undervisa direktintegrerade nyanlända elever i det ordinarie undervisningen. Vidare är syftet att få ökad förståelse för de möjligheter och svårigheter lärare upplever kring direkintegrerade nyanlända elever utifrån sin egen undervisning. För att uppnå detta syfte har semistrukturerade kvalitativa intervjuer använts som metod. Resultatet visar att lärarna använder många olika didaktiska verktyg i sin undervisning. Det framkommer även att lärarna använder ungefär samma didaktiska verktyg oberoende av årskurs. Det visade sig även att lärarna upplevde många svårigheter i verksamheten med direktintegrerade nyanlända elever. De möjligheter som de beskrev var betydligt färre. Svårigheterna innefattar allt från tid och arbetsbelastning till ekonomiska frågor. Möjligheterna i studien berörde till största del frågor rörande resurser som andra pedagoger. Frågor som behörighet och fortbildning samt undervisning på elevernas första- och andraspråk diskuteras.

    Pedagogers arbete med nyanländ elev: En studie om hur klasslärare beskriver olika pedagogers roller och arbetsuppgifter med en direktintegrerad elev och kommunikationen mellan pedagogerna2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The aim of the study is to investigate how class teachers describe the different educators who work with a new newly arrived student, their roles and tasks. The study is also about how class teachers describe the feedback between the different educators. There were qualitative interviews with four class teachers at various schools in north Sweden who have or have had a directly integrated newly arrived student in the class. Because the study is relatively small, it only gives an insight about witch educators work with a newly arrived student and how the communication looks between the educators. The results show similar responses of class teachers, that is, it does not differ as much which educator are involved and how the feedback looks.

    Olika vägar in i engelska: En fallstudie med fokus på hur lärandeaktiviteter används för att gynna engelskaspråkinlärning i årskurs 3 i svenska2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Detta arbete är en fallstudie av videografisk natur som ger inblick i vilka aktiviteter och vilken typ av kommunikation som sker i en engelskalektion för de yngre åldrarna. Filmen gjordes i ett klassrum i årskurs 3 och gav inblick i hur en lektion kunde se ut och vilka aktiviteter som eleverna fick ta del av. Bakgrunden till detta är att allt fler lärare som anställs i skolan saknar pedagogiskutbildning och det är därför av intresse att se hur engelskalektionerna kan se ut. Undersökningen visade att det fanns ett fokus på skriftspråkspraktiken, det vill säga på både produktion av text samt läsning. Resultatet visade också att det talade språket inte tar lika stor plats i undervisningen. Arbetsspråket för undervisningen var inte engelska utan istället användes modersmålet som ingång till språkinlärningen. Utifrån studien är det troligt att läromedlet har en stark påverkan på lektionsinnehållet och strukturen av lektionen.

    Konstnärliga entreprenörers framgångsfaktorer: En kvalitativ studie om att identifiera framgångsfaktorer förkonstnärliga entreprenörer2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Konstnärskap och entreprenörskap är fenomen som båda kännetecknas genomskaparlust, hängivenhet, fritt och självständigt tänkande. Trots att det finns en dellikheter sinsemellan konstnärer och entreprenörers personlighetsdrag råder det likasåen missvisande bild vad gäller entreprenören som personlighetstyp. Den beskrivs oftasom en extraordinär, stor risktagande individ som skiljer sig från mängden. Inomkonstnärskretsar däremot kan det snarare upplevas smaklöst att tjäna för mycketpengar på sin verksamhet och det är likaså vanligt förekommande att som kreatör tvivlapå sin kompetens inom området. Dessa föreställningar kan rimligtvis skapa starkaberöringspunkter för den som driver en konstnärlig verksamhet som utöverkonstnärskapet sannolikt även behöver vara entreprenöriell för att lyckas ekonomisktoch framgångsmässigt.

    Studiens syfte var att belysa några utmärkande framgångsfaktorer som kan varaviktiga för konstnärliga entreprenörer. Undersökningen gjordes genom en kvalitativforskningsansats där fyra olika konstnärliga egenföretagare samt en ännu ejföretagsverksam konstnär intervjuades utifrån studiens syfte. Respondenternas svarsammanställdes och analyserades därefter med stöd av vetenskapliga forskningsteoriersom huvudsakligen bestod av ett ramverk skapad av Philip A Wickham. Ramverket utgickifrån tretton avgörande framgångsfaktorer för generella entreprenörer.

    Undersökningen kom fram till att de medverkande egenföretagarnas utmärkande framgångsfaktorer var; hårt arbete, engagemang för andra, självständighet,att vara aktiv på sociala medier, att ha en nyfikenhet samt en vilja och strävan attutvecklas. Utifrån ramverket sammanföll en del av faktorerna med konstnärligaentreprenörers framgångsfaktorer och andra bara till en viss del. Det som däremot intekorrelerade lika stark med den generella entreprenören var faktorer som; självsäkerhet,motståndskraftig samt en bekvämlighet med att besitta makt.

    Låtskrivare = Entreprenör?: En kvalitativ studie om likheter mellan föreställningar om låtskrivare och entreprenörer2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of the study is to examine similarities between the role as a songwriter with the role as an entrepreneur, as well as the conceptions about working with songwriting. To examine this three questions was asked:

    • What similarities are there between the role as a songwriter and the role as an entrepreneur?

    • What characteristics are described as important to succeed as a songwriter compared to those of an entrepreneur?

    • What conceptions are there about working with songwriting?

    As a foundation for the thesis the history of the music industry is depicted in its own chapter with focus on the sales of music from the 15th century until today. The chapter describes how the music industry for a long time used sheet music as the main way to distribute new music. In the end of the 19th century the record industry started to emerge with the development of record players. During the 20th century the industry went through a lot of changes where new technology like the radio and the TV became important channels to reach a bigger audience. In the beginning of the 21st century the record sales plummeted as the music market became more and more dominated by different streaming services.

    The thesis empirical data is based on eight interviews, including a group interview, conducted in Los Angeles with four Swedish and seven American informants. It is also based on a forum thread from a Swedish music forum on the internet. The results from the interviews are first described in an overview and then divided into three categories; aspiring songwriters, songwriters in the music industry and informants working with songwriters. The results from the interviews shows that a songwriter should be a good person to collaborate with, be good at establishing important contacts in the music industry, and pay attention the administrative work of accounting, contracts and agreements. From the forum thread of the music forum disappointment is expressed about how DJ’s do not single handedly write and produce all the music they are attributed to in the media.  

    The analysis shows that professional songwriters have much in common with entrepreneurs because they both need to take risks, be creative, and start business. The similarities between the conceptions of what is required to succeed as a professional songwriter with what it takes to succeed as an entrepreneur includes having a good idea, having a supportive environment as well as being involved in marketing, sales and administration. Furthermore, the analysis shows that the work of songwriting is often glorified or overlooked, which creates misleading representations of what the work of a songwriter actually consists of.

    Förskoleklassen i förändring: En kvalitativ studie om implementeringen av det centrala innehållet i "språk och kommunikation" i förskoleklassen2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Enligt tidigare forskning har förskoleklassen haft ett otydligt syfte och dess uppdrag har osynliggjorts i skolans styrdokument fram till år 2016 då verksamheten fick ett centralt innehåll. Detta har varit problematiskt för pedagogerna då det inte har funnits specifika direktiv kring vilket innehåll de ska arbeta med. Med detta som bakgrund blev studiens syfte att öka kunskapen om vad som formar verksamma pedagogers arbete med läs-, skriv-, och språkutveckling efter implementeringen av det centrala innehållet. Metoden för studien var intervjuer där deltagarnas uttalanden analyserades med hjälp av von Wrights (1983) handlingsteori. Resultatet visade att implementeringen av det centrala innehållet tydliggjorde verksamma pedagogers arbete med läs-, skriv-, och språkutveckling. Resultatet fann även att flera faktorer påverkar detta arbete då läroplanen fortfarande är tolkningsbar och pedagogernas åsikter om kunskap, arbetsmetoder och innehåll har en avgörande roll för arbetet med detta.

    Undervisning under utveckling: -Lärares tillvägagångssätt för utvärdering av den egna undervisningen i matematik2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Syftet med studien är att fördjupa kunskapen om hur lärare, i årskurs 1-3, uttrycker att de går tillväga för att planera, utvärdera och utveckla den egna matematikundervisningen. Genom att se till faktorer som kan påverka planerings- och utvärderingsprocessen fördjupas förståelsen av det som sker. Studiens datamaterial samlades in genom kvalitativa intervjuer med åtta matematiklärare verksamma i årskurserna 1-3. Materialet har bearbetats genom systematisk textkondensering och analyserats utifrån de teoretiska utgångspunkterna som utgörs av en modell för lesson study samt ramfaktorteori. I resultatet framgår avsaknaden av ett systematiskt arbetssätt för utvärdering av undervisningen. Något som påverkas av ett antal ramfaktorer såsom tid, antal elever och möjligheten att utvärdera med sina kollegor. Avslutningsvis diskuteras resultatet i förhållande till tidigare forskning.

    Lärare till elever med svenska som andraspråk: Åk 1-3 lärares röster om sin undervisning av elever med svenska som andraspråk2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Studien undersöker hur fyra klasslärare i åk 1-3 organiserar sin undervisning för att utveckla det svenska kunskapsspråket hos elever med svenska som andraspråk. Bakgrunden behandlar synen på ämnet svenska som andraspråk och hur den förändrats med tiden. Studien lyfter fram likheter och skillnader i lärarnas beskrivningar. Dessa analyseras sedan med stöd av tidigare forskning och en teoridel som bygger på Jim Cummins sammanställning av forskning på ämnet. Resultatet visar att lärarna lyfter kartläggning och kontakt med vårdnadshavare till elever med SVA som viktiga förutsättningar för att skapa undervisning som utvecklar elevernas kunskapsspråk. Det framkommer även att lärarna vill organisera undervisningen så att elevers modersmål får en större roll i undervisningen, men att det inte alltid görs. Samverkan mellan klasslärare och modersmålslärare beskrivs som en förutsättning för att inkludera elevers modersmål i helklassundervisningen.
