Access to the market - a question of collaboration?
When contemplating entering an alliance the rationale behind the decision should differdepending on the size of the companies involved as well as on other important factors. The importantfactors influencing the decision are related to the resource pooling potential of the alliance,the power structure along with the business network the companies are a part of. Theanalysis has shown proof of a need for cooperation if one wish to succeed in the telecommunicationindustry and it has also determined which resources that are deemed to be most important toget in touch with, for our study object, to facilitate its access to the market. Those resources aredefined as a direct channel to the customer, funds/capital and the access to relevant businessnetworks. To get in touch with these lacking resources, three alternative approaches has beenproposed; all of them involving a strategic alliance decision.
Interna processer : Modell för ett effektivt returstålsflöde
The last decade has created an increasing pressure on companies to decrease their impact on the environment and to increase their effectiveness of recycling the company?s resources, especially for the steel industry. Companies have also started to realize the economic aspects of an effective internal reverse logistics. In the past the value of an effective internal reverse logistic was something that companies tend to underestimate and there are few academic studies done in this area. The purpose of this essay has been to identify key factors to create an effective in plant storage, transport, sorting and handling of returned steel. From these factors a generalized model for creating an effective return steel flow will be developed.
Att förlora en förälder i cancer-En kvalitativ studie över ungdomars behov av professionellt stöd
The aim of this study was to review six professionals supporters work to support adolescents in grief, and if this support is the kind of support adolescents actually need. These professional supporters are two hospital social workers, two hospice social workers and two support group leaders. The questions included in the work are; How does the professional support look like for adolescents aged 12-18, who has lost a parent in cancer? Are the adolescents getting the support they need from these professionals? The study is based on qualitative interviews based on interview guides, which where then analyzed thematically and linked to previous research and grief theory. The result indicate that adolescents may need different forms of support when their parent is dying or has died.
Igensättning av övre spalten i centrifugalpump
This report focuses on the upper slit. The upper slit is located between the impeller andthe drive unit. The slit design depends on pump type and application. However it isuncertain why the design varies, The purpose of this report is to clarify why the designvaries and to recommend an improved slit design.A research has been done; information was gathered from interviews, but also fromsearching of databases and studies of drawings, reports and documents. The originalpurpose of the slit was to prevent twining around the driveshaft, and prevent dirt fromentering the cooling system.
Kartläggning av materialflödet i Peabs försörjningskedja till byggarbetsplats med SCOR
The construction industry has not undergone the same logistical development as the manufacturing industry; this, in combination with increased material price, leads to the fact that the construction industry must be improved. This master thesis is a part of the research cooperation Brains & Bricks goal of reducing production costs for the construction sector by 25 percent. Brains & Bricks is a cooperation between Linköping University, Peab and Katrineholms municipality. The master thesis aims to identify improvements in the flow of material, the Supply chain operation reference, SCOR, model has been used and the work has been carried out on one of Peab?s construction sites. At present the business is characterized by bad communication both between the construction site and the office as well as between the construction site and suppliers.

SUMMARYInventory of raw materials holds an important role in companies within the manufacturingsector. The inventory works as a buffer that secure the supply of materials to the productionunit. The aim of the inventory is to ensure that the company is able to meet the customers?demands despite fluctuations and variations in the material flow. The size of the warehouseand the layout are physical limitations for the quantity of articles that can be stored.
Tillämpning av en markprofilmodell för hydrologiska beräkningar i avrinningsområdesskala
There is a great need to reduce nutrient leaching from arable land into lakes and oceans. By using several different types of models it has previously been possible to describe nutrient losses in a catchment area with a minimum unit of sub-catchment level. At present, it is instead desirable to model a smaller catchment with an opportunity to re-connect the results to the corresponding fields in the catchment. Such models already exist but they are not fully able to properly describe Swedish conditions and land characteristics in our region.With the approach of creating such a model, SLU has developed a project with this work as its first stage. The model is expected to be created under the working name SWE-model which stands for Soil Water Environment and is in this first stage supposed to apply the SOIL model in catchment scale. During the procedure to describe the first step in the process of developing such a model adapted to Swedish conditions and which works in the catchment scale with an area of about 10-30 km2, focus has been set on calculating the transport of water flow from different hydrological response units. Regardless of the processes occurring in the soil after the water has been added, it is assumed that all the water which flows from each simulated unit is drained.In the first step the hydrologic response units were identified based on land use and soil type in the study area. With the help of a script with functions that retrieve and transform data, certain units were chosen for simulation. The script was also created in this project. Finally, the model results were aggregated and summarized for each unique unit, for each sub-catchment, and also for the whole catchment.From the results it is possible to see similarities in the flow dynamics between modeled and measured data. The efficiency coefficient has been calculated to correspond to the mean of the measured values for the whole simulation period. With an automated calibration process the model should be able to perform better. The volume error gives an indication of overestimation from the model..

Trådlös strömning av en ljudsignal till multipla mottagare
I detta examensarbete har det undersökts vilken teknik för trådlös kommunikation som passar bäst att användas då en ljudsignal ska strömmas trådlöst till multipla mottagare. De tekniker som jämfördes var Wi-Fi och Bluetooth. Andra tekniker för trådlös kommunikation, ZigBee, ANT+ och NFC, valdes bort för att deras maximala datahastighet eller räckvidd inte var tillräcklig. 3G och 4G valdes bort för att det krävs en licens för att få använda dessa. Som mottagare skulle i första hand Android- och iOS-mobiltelefoner användas.
Kunskapens konstellationer: om ämnesanalys och tvärvetenskaplighet
The aim of this study has been to discuss ideas of knowledge within classification theory and subject analysis in the light of theories of fundamental changes in the production of scientific knowledge. Guiding questions have been: How have the conditions of knowledge production changed? How has interdisciplinarity as part of this development evolved? What assumptions lie behind theories of classification and subject analysis? How do these stand in relation to the alleged changes in the production and understanding of science? Three works about the changing conditions for knowledge production and the growth of crossdisciplinarity have been presented and discussed. These works stress the loosening up of boundaries between traditional knowledge domains and open up for discussions about how to organize knowledge production in the light of these changes. In the study it is argued that their works also could open up for discussions about the way knowledge is organized for retrieval purposes.
Translokation av större vattensalamander : -bevarandestrategi eller riskåtgärd?
This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.
Nyfikenhet i skolans värld : Vad elever i montessoriklass beskriver som lustfyllt lärande
Studien har genom intervjuer i fokusgrupper undersökt vad elever i montessoriklass erfar som lustfyllt i sin lärmiljö. Elevernas svar har satts i relation till den forskning som finns kring motivation och framgångsfaktorer för lärande samt till montessoripedagogiken.De teorier som studien utgår ifrån är olika motivationsteorier, teorier relaterade till motivation samt montessoripedagogik. Även framgångsfaktorer för lärande beskrivs. Tillvägagångssättet i analysen av fokusgruppsintervjuerna har inspirerats av fenomenografisk metodansats. De två forskningsfrågor som studien ger svar på är vad elever på mellanstadiet och högstadiet, i de undersökta montessoriklasserna, framför som orsaker till att de känner nyfikenhet att lära sig mer i skolan, samt vilka av dessa faktorer som är kopplade till montessoripedagogikens principer, och om de går att överföra till all undervisning. Resultatet av studien visar att eleverna pekar ut läraren som viktig för huruvida de ska känna nyfikenhet och lust i lärandet.
Kommunikationens betydelse : fallstudie på införandet av balanserade styrkort i Gotlands kommun
This study raises the question how the implementation of the balanced scorecard in the municipality of Gotland has been influenced by the way of communication. A case study is made in the administration of Social-and care management on Gotland. We have been focusing on two different ways of communication. The first one is Shannon and Weavers model where communication is explained as a transmission of a message through a channel to a receiver. The other one is sensemaking where it is focal to give the information meaning.

Askåterföring värt besväret? : en fallstudie av följderna av Stora Ensos försöksverksamhet med askåterföring
This thesis reports on a case study of a forest company, Stora Enso, and their experience from a number of trials and experiments with ash recycling. A literature survey and a total of eleven in-depth interviews were carried out. Ash recycling was found to be the concern of three different divisions of the company. The pulp industry which produces the ash, the forest division which would be responsible for identifying land and spreading the ash, and Stora Research, which has had a major part in the design and implementation of research trials. Lacking an overall company decision on ash recycling the matter is left to the individual divisions.
