Kulturförmedlare eller pedagog?: Yrkesroller och yrkesidentiteter på integrerade folk- och gymnasiebibliotek

In these days we can witness a growing number of combined school and public libraries in Sweden. It can be explained as an economy measure or as an attempt to develop the library work. The aim of this thesis is to picture how working in combined libraries affects high school librarians? own apprehensions of their professional identity. The results are based on in-depth interviews made with four high school librarians, working not only towards the students but also the public.

Förberedelseklass eller direkt integrering?  : En jämförande studie om hur två skolor i Södertälje kommun med olika arbetssätt arbetar med att integrera nyanlända högstadieelever i den svenska språkundervisningen

The aim of this essay is to examine how two different schools in Södertälje municipality are working to include and integrate newly arrived high school students in the subject Swedish as a second language. I will do a comparative study in which I study the teachers? completely opposite way of working to integrate newly arrived school students in the subject Swedish as a second language. I have used a qualitative method where I have conducted interviews. My main theory is Peder Haug's (1998) theory.

Borta bra, men hemma bäst? : En studie om ledarskap i en interkulturell kontext

The aim of this thesis is to create an understanding about how and to what extent a Swedish expatriate manager needs to adapt his/her leadership in accordance with the culture of the host country. Thus shall different managers? perceptions of experienced management overseas be studied. To accomplish our aim, three different problems have been designed. These are as follows: In what way does the manager?s earlier experiences and knowledge about expatriation affect her or his leadership in a new cross-cultural context? How does the culture of the host country affect the expatriate manager?s leadership? How does the expatriate manager handle contradictory demands: that is differences in expectations from subordinates and the higher management? We have chosen to use an abductive approach in order to do a qualitative study and we have therefore conducted eight case studies to create a foundation for distinguishing patterns.The case studies are based on eight Swedish managers with experience from expatriation. The theoretical framework is structured upon three main themes including; knowledge and skills a global leader needs to possess, the relation between the leader and subordinates, and contradictory demands.

Att välja prognostiseringsteknik

Det finns många olika Data Mining-processer som kan tillämpas i ett Data Mining-projekt. Fördelen med att använda en Data Mining-process är att projektet blir strukturerat, processen kan hjälpa till att minska risker som annars kan uppstå och kan medföra att projektmålet förändras. Data Mining-processen som studien har undersökt är generell och studien försöker därmed precisera olika faser av processen, för att anpassas till ett prognostiseringsprojekt.Studien utvärderar den preciserade prognostiseringsprocessen genom att följa och dokumentera ett prognostiseringsprojekt på en tillverkningsindustri. Studien analyserar teoretiskt vilka implikationer tillverkningsindustrin kan möta och även om studiens framtagna process är tillämpningsbar i detta fall. Studien visar att det på en teoretisk nivå går att genomföra studiens preciserade Data Mining-process och visar även vilka risker som kan uppkomma om ett prognostiseringsprojekt inte följer en Data Mining-process..

Utvärdering av en beslutsåterkopplad kanalestimator för tredje generationens mobiltelefonisystem

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER). An improvement is only seen when the BER becomes much lower than what is common in real situations. In conclusion DDCE is complicated, involves many mathematical operations and gives insignificant improvement of SNR when BER takes common values. It is legitimate to question if it is possible to use the method in a real mobile phone system..

Nitrat i grundvattnet : Modellanalys av vattenflöde till Hörviks vattentäkt

A well, situated on Listerlandet in the western part of Blekinge in Sweden, has a very high content of nitrate. Water with a too high content of nitrate is hazardous to human health, in particular to small children. The area surrounding the well is mostly drained agricultural land with some larger farms for chicken and mink. The well takes its water from the bedrock and is deeper than most other wells affected by nitrate. The bedrock in the area is dominated by limestone with a relatively high flow of water.This thesis was performed in order to find the source of the nitrate.

Status i grupphierarkin : om barns sociala interaktioner

In this study the author attempts to identify factors that are determinants for why some pupils in Swedish grade school have high status in comparison with their peers. The study takes on the characteristics of both an ethnographic and a literature study by comparing the findings of interviews carried out with students of a first grade class with previous research. The study identify several tools for analyzing of how status may be understood in specific situations.The study also finds that important factors for gaining high status amongst children in aschool classes might be the ability to apply access strategies to get accepted in social interactions, such as game play, have the ability to create games that are enjoyed by peers and social skills, to name a few. Overall the study shows that children's game play with each otherare crucial for their social interactions and their social position. The study also show that children that have earlier established relationships with other children in a specific group alsohave a better opportunity to establish a high status position..

Identifiering av områden med risk för fosforförluster genom ytavrinning : metodutveckling med GIS

The eutrophication of lakes and seas with the algal bloom and deficiency inoxygen that follow, has been given priority by the Swedish government as oneof 16 environmental objectives. The purpose of this project was to develop a toolbased on a simple model, limited amount of data and geographic informationsystem (GIS) to identify areas with risk for phosphorus losses due to surfacerunoff. This tool can act as a decision support to decide where appropriatemeasures should be applied with the aim of reducing phosphorus losses and bythat the eutrophication.The method that has been used is a combination of two models, one calculatingthe potential erosion while the other one identifies areas of erosion (net erosion)or deposition. This ability is of great importance because potential erosionshould be calculated on areas with net erosion. Areas with high potential erosionhave an increased risk for phosphorus losses due to surface runoff.The potential erosion was calculated based on factors which describe how topography(LS), land use (C), soil type (K) and precipitation (R) effect the erosion.All of them have been modified to a greater or lesser extent.

Svenska livsmedel - varför? : restaurangers, grossisters och offentlig upphandlares inställning till livsmedel från Sverige

The background of this research is that Swedish food products have hard to compete at the home market, depending on imported food products that increase more and more for every year that pass by. The ethic values LRF associate with Swedish food products, many customers have hard to put in relation with condition of foreign agriculture. Most customers today inquire high quality, safety and convenience in the food which they are eating. The source of their food seems to have less meaning. Many restaurants and bigger households appreciate Swedish food products and wants to buy them but price differences against foreign wares are to high. We have done oral interviews with wholesale dealers, restaurants, public purchasers and with different market organisations, there we have discussed buying strategies, the way they see the primary producer, the conscious of guests, choice and attitudes to Swedish and foreign products, distribution of power in the food market chain and to what position and suspension, they want the ranks of suppliers to have. The result shows the share of imported wares within restaurants and bigger households are at a high level and will continuing increasing. Within these sectors the final consumer in many cases put less effort in the origin of the raw source of food.

Könsselektering av spermier från lantbrukets husdjur

Millions of preselected progeny have been born since the development of The Beltsville Sperm Sexing Technology 1986. The method is based on flow cytometry and sorting is done on the basis of DNA difference of the X- and Y-chromosomes. Preselection of progeny provides an opportunity to obtain genetic gain and increased production as well as increased animal welfare and decreased environmental impact. However, the method is associated with low fertility, high costs and uncertainty whether the sorting process contributes to DNA damage and thereby results in genetically impaired progeny. Today, sex sorted sperm is only commercially available in the bovine industry, due to the fact that bull sperm is more suitable for selection than sperm from other species.

Att överföra geospatiala data från en relationsdatabas till densemantiska webben

Semantiska webben är ett begrepp som handlar om att göra data tillgängligt på ett sätt som gör att datorer kan söka, tolka och sätta data i ett sammanhang. Då mycket av datalagring idag sker i relationsdatabaser behövs nya sätt att omvandla och lagra data för att det ska vara tillgängligt för den semantiska webben.Forskning som genomförts har visat att transformering av data från relationsdatabaser till RDF som är det format som gör data sökbart på semantiska webben är möjlig men det finns idag ingen standardisering för hur detta ska ske.För att data som transformeras ska få rätt betydelse i RDF så krävs ontologier som beskriver olika begrepps relationer. Nationella vägdatabasen (NVDB) är en relationsdatabas som hantera geospatiala data som används i olika geografiska informationssystem (GIS). För samarbetspartnern Triona var det intressant att beskriva hur denna typ av data kan omvandlas för att passa den semantiska webben.Syftet var att analysera hur man överför geospatiala data från en relationsdatabas till den semantiska webben. Målet med studien var att skapa en modell för hur man överför geospatiala data till i en relationsdatabas till en RDF-lagring och hur man skapar en ontologi som passar för NVDB?s data och datastruktur.En fallstudie genomfördes med dokumentstudier utifrån en inledande litteraturstudie.En ontologi skapades för det specifika fallet och utifrån detta skapades en modell för hur man överför geospatiala data från NVDB till RDF via programvaran TripleGeo.

Reproduktion och reproduktionsproblem hos taxtikar

Artificial insemination (AI) has had a great influence on the development of pig production and is today widely practiced (Gerrit et al., 2005). With AI, genetic progress can at a short period of time be spread worldwide compared with using natural service and the best boars can be intensively used. This is also one of the biggest risks with AI; the impact of semen containing a genetic disease or contamination of pathogens can be enormous. Fortunately, it is a small risk of disease transmission due to many tests of the boars and the semen before use (Maes et al, 2008). It is important that the boars used for insemination have good breeding values along with good reproduction features and have good fertility results (Robinson et al., 2005).

Konstruktion och byggnation av testfixtur för 10Gbit/s transpondermoduler

This thesis for the Master of Science degree was performed at Solectron Corporation in Norrköping. The background for the thesis was a need to develop and build two test fixtures to automatize testing and adjusting of transmitter modules (TX-fixture) and receiver modules (RX-fixture) which are head devices in DWDM-systems. The basic elements for the test fixtures are: Test board, switch board and DC/DC board. The main function of the test board is to handle communication between the transmitter and receiver modules and supply voltage to these modules. The test board was insufficient and modified with a microprocessor to handle the communication between the PC and the receiver module.

Högt hus i Chongqing/Kina - ett bostadsprojekt

This is a project showing a proposal on how a high-rise building gains qualities similar to middle rise houses of 7-9 stories. The closed, isolated and often anonymous life in the high building opens up through gardens. The resident meet the outdoor environment on the balcony, or has direct access to a garden.Instead of moving in a closed core, the resident will meet the climate and outdoor conditions as soon as he or she leaves the apartment.The project consists of two parts, where the first is presenting a building proposal, the second is expanding the knowledge through background research. The topics are history concerning the skyscraper and the skyscraper globally, closing up with the situation in China..

Framtagning av prototyp för att läsa och dokumentera kundspecifikationer

To increase the quality in their products ABB is working towards a cleared order concept. That means that all customer specified options are to be known before they start with order calculations and construction. As it is today they use paper checklists to achieve this. One order may have several reactors, and for a reactor there can be several different alternatives. For each alternative a new checklist must be filled out.As of today all reading of the customer specification and checklist fill in with is done by hand by different persons, and sometimes the same data is read more than one time.
