I ett samhälle där relationer, även sådana av icke romantisk karaktär, har en central roll imänniskors liv är det viktigt att försöka förstå vad som ligger till grund för individers engagemangi relationer. The Investment Model säger att engagemang i relationer ökar då individerupplever ökade belöningar, minskade kostnader, färre attraktiva alternativ samt att deinvesterat mycket i relationen. I föreliggande tvärsnittsstudie undersöktes 61 grundskolelärarei Göteborgs Stad, med hjälp av the Investment Model, angående upplevt engagemang tillsitt arbete via ett frågeformulär. Studien visade att grundskolelärare med längre anställningstidupplever att de investerat mer i sitt arbete än vad de med kortare anställningstid angav..

Distrilux International AB, a company within the Electrolux-group, works among other things with storing of products from other companies in the Electrolux-group. This rapport contains a cost analysis of the two Distrilux warehouses in Motala and Mariestad. The company offers five services in these warehouses, in-loading of products from a local factory and from external factories, storing, out-loading of products to Sweden (domestic) and for export. Since there has been some hesitation of the accuracy of the price-model of today, a master's thesis has been advertised. The purpose of the thesis has been to investigate the agreement of the price-model of today and the apportionment of the costing in warehouses.The main problem is to determine which activities is to be considered important in the price-model.

The predominant forestry harvesting method is based on the harvester-forwarder method, theharvester folds, branches and cuts trees, and sorts the logs into piles, while a forwarder transportsthe logs to a landing area.This master thesis work is about realization of a dynamic forwarder simulation model, and itspurpose is to provide an integrated forwarder simulation model in MATLAB/SimMechanicswhere the forwarder is based on a concept using pendulum arms to connect wheels and chassis.Active suspension control is developed and implemented into the simulation model, and finallycompared in simulation with passive suspension.In a first step, an integrated forwarder simulation model is developed, containing a simplifiedforwarder model, a tire-to-ground interaction model and a test track model. The simplifiedforwarder model is based a rigid multi-body system with a spring-damper suspension of thependulum arms. The tire-to-ground interaction model calculates the reaction forces, friction fromthe ground and applies the propulsion force. The test track model is a simplified version of thereal test track in Skogforsk. The propulsion wheel torque control is used to regulate theforwarder speed.

Regional European Offices with the purpose to represent regions and municipalities in the EU-system have had a substantial expansion over the last years. One example is the North Sweden European Office for the counties of Norrbotten and Västerbotten, consisting of seven different headmen who are representing both the private sector as well as the public system. This diverse leadership representation makes North Sweden a very good example on a so called Quango, organisations that stand under simultaneous influence from both public and private sectors. These Quangos opens up new possibilities to solve public problems, but they also bring together two different working models which is not always easy to handle for a Quango. According to earlier surveys some characteristic Quango problems within North Sweden exist, for example the ability to prioritize and thereby be as effective as possible.

Making the work in the public sector more efficient is something that has been seen as necessary during the later years. One way to do this on municipal level has been to apply solutions former used mostly by private companies. The organisational parts have also been adjusted to existing conditions in this work of change. For example more and more municipalities have come to use the purchaser-supplier model since the beginning of the 1990's. Norrköping, Linköping and Motala have been chosen in this essay for a closer study of the effects of the changes of the 90's, from an efficiency point of view.

In this paper I have sought a suitable level of abstraction in my models describing the landscape; the models are made to be viewed from eyelevel. Because of the spectator being ?in the model? the objects included need a certain degree of realism. I have sought what is needed in the model to be able to comprehend that the model is showing a landscape. Some details might be unnecessary.

Foreign invested SMEs have recently become increasingly interested in China. The enterprises are in this report categorized as second wave companies since they follow the footsteps of previous pioneers, of which mostly were larger companies. The ambitions of the SMEs are either to sell products on the ever expanding Chinese market or to utilize the potential of low cost production for global markets. The existing literature is fragmented and solely based on the experience of larger companies. We believe that SMEs are facing new and different challenges, and thus a new generic theoretical frame work is desirable.

This bachelor thesis project has been executed at Outotec Sweden AB in Skellefteå. Outotecs main business focus is selling mineral and metal processing technologies. A rest product from the metal process is particle-polluted gas and cyclone designs are today the most commonly used abatement device for particle control. A cyclone provides a simple design with high efficiency particle percolation by using air streams.The purpose of this work is to reduce the time it takes create new cyclone designs in Outotecs projects. An extensive construction work is needed for every new cyclone order due to new designs.

Diagnosis means detection and isolation of faults. A model based diagnosis system is built on a mathematical model of the system. The difficulty when constructing the diagnosis system depends om how the model is formulated. In this report, a method is described that rewrites the model on such a form that the construction of the diagnosis algoritm is easy. The model is transformed by two state space transformations and the result will be a system on state space form where one part of the system becomes easy to supervise.

An important task for Region Skåne is to allocate resources to the health care districts. From 1999 to 2002 Region Skåne used needs-based resource allocation as a model for allocating resources. In a needs-based resource allocation individuals with the same socioeconomic and demographic characteristics are assumed to have the same level of need and are therefore allocated the same amount of resources. During the period of needs-based resource allocation a matrix model was used as a method. In the matrix model individuals were divided into cells after each combination of the socioeconomic and demographic variables.

The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.

This thesis intends to analyse conditions for a successful implementation of consociational democracy, as a democratic model in Afghanistan. The lack of critical reviews regarding the democratisation-process in Afghanistan initiated the purpose of this study.Lijpharts democracy model was used as the basis in the comparative study. Along with empirical evidence regarding how the complex process of democracy in Afghanistan is progressing, the study investigated whether the identified conditions occurred or not.The choice of which democracy model to use can be crucial for the democratic possibilities to even survive and become established in conflict-affected communities. The principle of consociational democracy is that it is an empirically based normative model that aims to organise the state in a way that works against the risks of majority domination and oppression against the minority.The empirical case study revealed that a majority of the conditions were not met, which then can counteract the possibilities for consociational democracy in Afghanistan. The study has critically examined the prospects for the success of consociational democracy in Afghanistan, and it can be assessed that there is a limited probability for a successful applying of this model..

The financial crisis in 2008, effected companies around the globe and forced them to change their operational strategies, in order to survive. Companies with international links needed to consider external effects and due to that adapt their strategies on a global level. Demands for goods and service were decreasing and companies could only manage the cost during a recession to not face bankruptcy. Organisations need to reconsider their optimal strategy as this will determine their future outcome when managing a crisis as the one in 2008. British Airways - Air Cargo is a global company with an international network which serves about 80 countries, with about 200 destinations.

Increased resource efficiency in an energy system could result in large economic and environmental benefits. Tekniska verken i Linköping AB (Tekniska verken) is responsible for the district heating network in Linköping. Their vision is to create the world?s most resource efficient region. An important step towards this vision is more efficient usage of produced heat, something which could be achieved through integration of a seasonal heat storage in the energy system.
