Lek och lekmiljöer : Förskollärares beskrivning av planerade lekmiljöers betydelse för leken

The purpose of this study is to gain knowledge and a broader understanding for how pre-school teachers describe the importance of planned play environments including in what manner children are given influence. By qualitative interviews with five pre-school teachers from four different units I was able to gather data that shows how the planning process concerning a specific play environment had worked and why it looked as it did. The results show among other things that the pre-school teachers viewed the play environment as a vital part of the daily operation and pointed out that it was of vital importance that it came from the children?s interests. Depending on how the play environment had been organized and what its purpose was it offered different amounts of affordances..

Eftersök av försvunnen person

Eftersök av försvunnen person ? ur hundförarens synvinkel. I arbetet har jag velat lyfta fram hur hundekipage fungerar som resurs vid eftersök av försvunnen person. Jag har försökt beskriva hur hunden används, dels hur hunden själv arbetar men även hur det är att vara hundförare och vad man som hundförare måste tänka på. På ett förhoppningsvis lättfattligt sätt har jag beskrivit MSO-modellen som är den arbetsmodell man utgår från vid eftersök av försvunnen person.

Silkesvante eller piska - Socialtjänstens och polisens insatser och samverkan kring kriminella ungdomsgäng

The purpose of this essay was to study social workers´ and polices contributions with criminal youth gangs and get an insight in how co-operation in the contributions between these governments comes to rank and works.To find out, we carried out a study with a qualitative design based on document studies and interviews with social workers´ and polices who were meeting youths in their work.Our findings were that it's hard to define a criminal youth gang. The social workers´ and polices have both individual and common contributions with criminal youth gangs. One of their most important lining is to prevent new recruitment of young people to criminality. The social workers´ and polices both have an intention to cooperate but they can?t agree about the method of work they shall use, ?the kid-glove or the whip?..

Automobike: en cykel med aktiv balans

During spring 2012, six students at the Royal Institute of Technology in Stockholm carried out agroup project in the field of mechatronics as part of the thesis for the bachelor degree. The resultwas a robot with active balancing and the purpose of this report is to describe the development,manufacturing and problems that arose during the project. The finished robot has two wheelsmounted in line with each other, like a bicycle. Measurement data from an accelerometer and agyroscope are used together in a complementary filter for determining the angle from the verticalplane. For balancing, a PID controller was used to control the rotation of a reaction wheel, whenaccelerating causes a straightening torque.

Virtuella Communities : Sociala faktorer i digitala miljöer

Virtual Communities is an increasingly common phenomenon on the Internet. Most of the Virtual Communities are operated and maintained on a non-profit basis with a direction towards entertainment. However, as more state administrated and commercial services become web-based, we believe that the number of Virtual Communities with a community-based or commercial direction will increase in a near future. In this thesis, we describe our participation in, and studies of, a number of Virtual Communities with focus on the IRC-channel ?3dfxsweden?.

International negotiation: pre-negotiation in Swedish
companies

International negotiation is the link between international planning and implementation. The ability to negotiate successfully may very well depend on the efforts being put into preparatory activities, leading to the purpose of this research, to gain a better understanding of pre-negotiation in an international context, by exploring, describing and partly explaining the process. Personal interviews were conducted with two Swedish international companies to obtain thorough information within the area. The collected data from these two cases are discussed, compared and then finally used to draw general conclusions. The study indicates the different issues that either occur or should be considered prior to the first formal meeting in an international negotiation.

Kreditgivning till lantbruksföretag : en jämförelse mellan Sverige och Danmark

In relation with structure transformation in farm companies with bigger animal population and pressure at the milk price, the farmers in both countries have to invest more money in the company to endure. This had conduct what more owners had seen grown requirements to invest in bigger population barns. The investment is necessary to retain stability in the economy for the companies, at that time when the profitability for small production barns decrease. This essay carries out through a case, there the activities main part are milk production. The present operation consists of 82 milk cows in long stall with a yield on 10 500 kg ECM. The idea is that the company should increase the activity to 180 cows.

Farmers´ decisions factors : a case study

This study examined the factors influencing dairy farmers´ decisions to invest in automated milking systems (AMS). The problem studied involves uncertainty, information and complexity for dairy farmers in specific decision contexts. The frame of reference in the thesis combines contingency theory and decision theory and is used in a qualitative analysis of a set interview with dairy farmers who have recently bought an AMS and salespersons from Delaval, one of the AMS suppliers.The aim of this study is to develop an understanding of the decision making processes of dairy farmers, and in particular to identify which types of factors influence the outcome of an investment decision in the technological development of a farm.The study uses Thompsons` (1967) theory about the structure that organizations develop to handle the input of information. Thus, interest is focused on how a farm business structure handles information in the AMS decision, investigating the differences in information with Delaval?s "feed first principle" system and Lely?s "free cow traffic" system.The results of the qualitative interviews with the dairy farmers who bought an AMS show that there are three important factors that influence the outcome: employees, suppliers and the owner.

Mervärdeskapande på Internet : En undersökning av Internetbaserade resebyråer

The purpose of this thesis is to examine whether Swedish, Internet-based travel agencies, acting on a consumer market are working towards creating added value for their customers. If that is the case, how and why do they use such a mode of operation.The theoretical framework was based on Grönroos´ ?Augmented service offering?, which treats added value as an addition to the core service. The services offered on five of the larger companies´ websites on the market were examined and 3 representatives of the five companies were interviewed.The study shows that 2 of the examined companies did not produce any added value, while 3 of the companies did produce added value for the customer. The added value was generated through packaging of core-, facilitating- and supporting services for the purpose of differentiating the company towards competitors and generating service fees..

HMGB1 ? en möjlig biomarkör för sepsis

Pyometra är en vanlig sjukdom hos äldre, okastrerade tikar. Oftast uppträder sjukdomen i efterlöpet då tiken står under progesteronpåverkan vilket gör livmodern mer mottaglig för bakteriella infektioner. Enligt studier är Escherichia coli den bakterie som vanligen isoleras från livmodern. Bakterierna härstammar troligtvis från tikens normalflora eller från urinvägarna. Kliniska symptom på livmoderinflammation kan vara sänkt allmäntillstånd, variga flytningar (om cervix är öppen), polyuri, polydipsi, feber, diarré och kräkningar.

Statusbedömning av asynkronmotorer

Induction motors, often referred to as the workhorse of the industry, play an important role in production today. Therefore, it's important to diagnose any faulty induction motor prior to failure to avoid costly and time consuming production stops.This thesis compares methods for diagnosing induction motors in operation, MCSA, Park's vector approach and the standard method used by Swedish industries today. By simulating broken rotor bars and short-circuit in one of the windings, each method is tested and the results are compared using matlab.The results need further verification due to uncertainties of the condition of the test motor, even though the experiment gives a hint of the different advantages of each method. A combination of the methods should be able to tell if the motor needs further examination..

Fjärrlåneverksamheten på Borås och Kalmar högskolebibliotek

The object of this essay has been to investigate the interlibrary loan service at the universitylibraries of Borås and Kalmar. For this purpose a quantitative and a qualitative methodhave been used.The main body of information consists of statistic data concerning the incoming interlendingorders for a three-month-period. In order to examine the circumstances under which theinterlending activity exists several interviews were made.The study showed that there are several important factors which together make up the complexitythat governs the interlending activity. What type of demand there is depends on theeducational level, whether the different study programmes have a broad or limited subjectorientation or not, and if the demand is of a constant or an inconstant nature. Well-establishedroutines at the information-desk and co-operation with the departments of the different studyprogrammes are important factors in keeping the knowledge of what books and serials areneeded up to date..

Missilstyrning med Model Predictive Control

This thesis has been conducted at Saab Bofors Dynamics AB. The purpose was to investigate if a non-linear missile model could be stabilized when the optimal control signal is computed considering constraints on the control input. This is particularly interesting because the missile is controlled with rudders that have physical bounds. This strategy is called Model Predictive Control. Simulations are conducted to compare this strategy with others; firstly simulations with step responses and secondly simulations when the missile is supposed to hit a moving target.
