Kulturanvändande bland Unga : En studie om kulturvanor, ungdomars livsvillkor och bibliotekets roll
The aim of this bachelor thesis has been to examine and develop our own understanding about how young people in Sweden (16-29 years of age), take part in cultural activities. As librarians it is important to know what kind of activities and interests this particular group has. With Pierre Bourdieu?s theoretical framework towards habitus and capital we are interested to see if there is a connection between one?s cultural use and background, if different access to capital with or within groups has an affect or not. With both statistics and interviews with people within our target, we believe this data has been sufficient enough to conduct a good and valid study.
Internkommunikation på Gruvön : Modern kommunikation inom industrin
The bulk of the research within the field of media and communication is concentrated at theforefront of development, studies focus on modern companies and modern communication.However, many people work in the industry, where the conditions for communication are partly different. The aim of this study is to explore the possibilities for internal communication that the employees have at the base industrial company of Billerud Gruvön, Sweden. How important do they feel that communication is? Can the internal communication within Gruvön be described as modern, where dialogue between the staff is possible, or as orders from the top down to the bottom of the hierarchal structure?These are our research questions:Which channels are used for communication within Gruvön, and how are they used?How important do the employees deem the internal communication to be?Can the communication within a hierarchal industrial company such as Gruvön be described as modern, where dialogue is at the center, or does the communication consist basically on orders from the top down to the bottom of the chain?Our research is based on the following theories: Communication, Organizational communication, Internal communication and Organizational culture. We have looked to earlier research such as the doctorates of Simonsson (2002) and Johansson (2003) to further our understanding.The methods used are interviews with operators, middle management and the informationofficer at Gruvön.
Russinen ur kakan: - uppföljning av kampanjer i byggvaruhandeln
The Swedish do-it-yourself (DIY) market has expanded in recent years and is today a SEK90 billion market. Competition is fierce, however, and the DIY retail chains compete over market share with extensive marketing campaigns. Advances in computer technology have made it possible to acquire and compile huge quantities of point of sale data. However, due to a lack of economic theories and statistical methods, this data cannot be effectively utilized and the effects of the campaigns are not measured in any detail. In this study a new method was used to examine the effects of marketing campaigns in the DIY consumer market.
Utvärdering av prototypen för ett kollaboratorium inom biblioteks- och informationsvetenskap
This study is a formative evaluation of a prototypecollaboratory for sharing data collection instruments inlibrary and information science (LIS). The aims were to findout: how the study participants, five hospital librarians,experienced the interaction with the prototype while workingwith predetermined tasks; and their views on the differentfunctions of the prototype collaboratory.Methods used for data collection was as a survey; followedby a think-aloud session where the participant verbalisedhis/her thoughts during the interaction with the prototype;and finally a semistructured interview. The survey wasanalysed with a frequency distribution, while the data fromthe other methods were analysed qualitatively by extractingthemes from the transcribed sessions.The results show that although the librarians expresseddifferent problems while working with the interface, mainlyrelated to the language in the prototype collaboratory anddifficulties with the page for applying metadata, all of themwere confident in being able to learn the system after using itfor a while. The librarians had a positive attitude towardssharing data collection instruments as well as comments inthe prototype collaboratory. At the same time, they wereaware that students and researchers might have differentabilities or incentives to work and share information.
Diskussioner inommatematikämnet : Kreativa och Imitativa diskussioneroch när de används i undervisningen
The purpose of this essay is to examine when teachers choose to discuss mathematics withstudents rather then just talk about mathematics. A definition where used to distinguish betweenan interaction that is not a discussion and an interaction that is a discussion. This definition hasbeen created by drawing ideas from other works into making a quite simple definition whichtherefore is easy to observe. The discussions are also separated into two different kinds ofdiscussions. The first and most common category of discussion are one where only imitativereasoning is used.
Livscykelbaserad miljövärdering av en ny kontorsbyggnad : En jämförande studie mellan två analysmetoder
This Master?s Thesis aims to illustrate in what ways the two Swedish environmental assessment tools, the Environmental Load Profile and EcoEffect differ and if performed valuations gives different results and environmental goals.The built urban environment causes about half the environmental loading in Sweden. The society?s ambition towards sustainable development has resulted in demands reducing the environmental load. One way to accomplish this change is with the assistance of tools for environmental assessment of the built environment.
Data och metodik för utbytesberäkning - en studie på Medelpads Skogsförvaltning
To manage the industry?s need of wood assortments in a optimal and cost effective way the forest companies need to have knowledge of the actual standing volume and the yield of the planned clear cuts. The mean volume of the trunk is also important since it is important for the contractors prices. Today the total volume are estimated either with Näslund (1940) or Brandels (1990) functions of volumes, and the yield is estimated with Rune Ollas (1980) function for trunks and stands. The purpose of this study has been to answer the following questions: How good is the yield forecast with data collected with currently used methods? How well can the yield forecasts became with data collected according to the instructions? How well can the yield forecast be with data collected according to the instruction and calculated with the program Aptan for theoretical bucking? The study has been initiated and financed by SCA Skog AB.The material consisted of a number of randomly selected objects ready for clear cut.
Klassning av fjällbjörkskog enligt FAO:s definition av skogsmark med hjälp av flygburen laserskanning
Sweden?s forestry legislation was updated in 2010 and a new definition of forest land was introduced. This definition was adapted to the one used by the Food and Agriculture Organization of the United Nations (FAO) for international statistics on the state of the world's forests. It is in short based on the lands ability to grow forest that reaches 5 meters, 10 % canopy closure and has a continuous distribution, according to FAO at least 0.5 hectares. A country-wide laser scanning is now carried out for the production of a new national elevation model; the laser data also provides information on forest height and density.
Bootstrap som hjälpmedel att öka noggrannheten och bedöma precisionen vid probitregression, med tillämpning på hörselmätningar
In many biomedical contexts, e. g. when evaluating hearing disorders, the data obtained can be described as pairs (x1, y1), ?, (xn, yn) where x is a quantitative variable and y a 0/1 variable whose probability of taking the value 1 is a monotonic function of x. One way of analysing such data is to perform probit regression; thereby two parameters, b0 (= the constant) and b1 (= the slope) are estimated; the interest centres around m = -b0/b1, i.
Går det att ställa om en lina för axelbearbetning på 30 min? : En fallstudie på Scania Transmission, Södertälje
Tillverkningslinan för växellådans ingående axel har funnits i sitt nuvarande utförande sedan sensommaren 2013. Omställningstiden för linan översteg med råge det önskade, vilket ledde till långa stopptider och förlorad produktionstid. Under de förutsättningar som rådde hamnar genomsnittet för omställningstiden någonstans i intervallet 3-4 timmar, men tider kring 6 timmar hör inte till ovanligheterna. Målet med uppdraget var att, på den observerade linan, sänka omställningstiden till 30 minuter samtidigt som produkternas kvalitet bibehålls. Ett delmål under arbetets gång var att skapa förutsättningar för att tidsvariationen minskas samt att det definieras hur omställningstiden på linan ska mätas.
Hantering av småskalig elproduktion : Utveckling av modell för dokumentation och elkvalitetsberäkningar
The interest in small-scale electricity in Sweden has increased strongly in recent years. The interest is noticeable both among politicians to increase the share of renewables in the energy mix, and among electricity consumers to partially replace purchased electricity with self-produced. This has resulted in a significant increase of electricity production in low voltage grids in recent years, and the trend appears to continue in the coming years. The majority of the new production plants are solar cells, followed by wind turbines, and it is also in these the greatest efforts are made in this paper.Distributed generation is often seen as something positive since it will contribute to reduced transmission losses and reduced voltage drop in the networks, and that it increases the share of electricity from renewable sources. In cases where the grids are not strong enough, or in other ways not adapted to manage the installed production, power quality may be adversely affected.
Förstärkning av bro 17-803-1 : En jämförelse av förstärkningsmetoder
AbstractThis master thesis was performed at Scania transmission department in Södertälje, where the manufacturing of gears is done. Today a large amount of manual handling is performed between the machining and the hardening process. Most of the manual handling is done at the heat treatment department. The purpose of this master thesis is to give a suggestion on how to reduce or eliminate the manual handling at the heat treatment department. The possibility to use the same packaging throughout the processes will also be investigated.
Flotation therapy for downer cows : a retrospective study of cases treated with flotation therapy at the Large animal clinic at the Faculté de Médecine Vétérinaire at Université de Montréal
There are about 700 000 dogs in Sweden. Roughly 70 % of the dogs are purebred and registered in the database at the Swedish Kennel Club (SKC). The database includes records of birth date, pedigree, offspring and results from e.g. veterinary examinations related to genetic health programs.Every year approximately 10% of the dogs die; most are euthanized by a veterinarian. Dog mortality data is stored as digital medical records at animal clinics and in insurance databases.Dog owners tend to register their puppy in the SKC, but they rarely report that the dog has passed away.
Kvalitet på vägdata : inventering av skogsbilvägars standard samt jämförelser med lokal bedömning och SNVDB.
During 2006 SNVDB (the national road data base for forestry) is being introduced to Holmen Skog. This data base contains all information about Holmen Skogs road systems. The information will then be used in different kinds of optimisation models which only produce correct and reliable results if the input data are of the adequate quality.
Today there are reasons to believe that road data is of various qualities. The forest roads are often in a bad condition and have to be improved before a planned harvest. The cost of maintenance and construction of new roads is a large part of the total harvesting cost.
Användning av LiDAR och ArcGIS inom skogsbruk i Sverige
Light Detection And Ranging (LiDAR) har under det senaste decenniet utvecklats mycket och används som datainsamlingsmetod vid inventering av skog. Lantmäteriet genomför mellan åren 2009 och 2015 en riksomfattande flygburen laserskanning över hela Sverige och den laserskanningen ska leda till en ny nationell höjdmodell (NNH). Data som genereras från denna höjdmodell kan nyttjas av skogsindustrin för att göra skogliga inventeringar. Programvaruutvecklaren Esri Inc. har utvecklat ett stöd för hantering av denna typ av data i deras nya version av ArcGIS, ArcGIS 10.1.
