Möjliga strategier för mobila tjänster

Problem: De teorier om strategier som finns idag och som används kan synas vara föråldrade. Då information skiljer sig från de traditionella tjänster och produkter finner vi ett behov att undersöka hur vidare strategierna kan användas inom den mobila kommunikationen och den nya ekonomin. Syfte: Syftet med denna uppsats är att skapa förståelse för möjliga strategier som kan göra mobila tjänster lönsamma. Metod: Vi har använt en kvalitativ undersökning med ett positivistiskt angreppssätt. Genom en abduktiv ansats kommer vi att föra en diskussion genom teorin samt empirin.

Vindkraftens påverkan på sin omgivning : En fallstudie

Purpose of this thesis is to study the impact of wind turbines on their surroundings. It also aims to analyze how the communication looks between the authorities, the planner and local residents prior to the establishment of wind turbines in Lännäs/Odensbacken in Örebro, where three wind turbines set up in a group.The results of this survey show that the participants experience themselves not as especially disturbed of the turbines in the form of large noise, shadows, and sleep disturbance indoors and outdoors. Participants felt that no change had taken place on the natural environment (52%) since the turbines became operational. It was 49% of participants had got no information about the establishment of Örebro Municipality, Örebro County Administrative Board or Wind Power Company. Scientists/­experts had the highest confidence of 86%, politicians and the media/journalists had least confidence.

Äldreomsorgens psykosociala arbetsmiljö : en studie av undersköterskor och vårdbiträden som arbetar med äldre på särskilda boenden

The purpose of this study was to find out how caregivers experienced their psychosocial work environment at three municipal homes for old people. The Copenhagen Psychosocial Questionnaire (COPSOQ) was used in order to study different dimensions of the work environment, and questions about health, sickness presence and sick leave were included. The questionnaire was answered by 86 out of 112 participating caregivers (77%). The results showed that the caregivers experienced high demands at work. The degree of feedback and influence at work was low, but they reported that their work was highly meaningful and that they usually received social support at work.

Uttagsbeskattningens förenlighet med etableringsfriheten : Borde man valt en annan väg?

Detta arbete består av designen av ett gränssnitt för webbplatsen whatismykidplaying.com. Designen var tänkt att ge hög användbarhet för målgruppen och testades av användare i ett think-aloud test. De fick testa och utvärdera hur väl gränssnittet fungerar och  deras feedback utvärderades och resultaten låg till grund för förslag på förändringar i gränssnittet, vissa som sedan blev implementerade. Studien har utgått från de olika stegen i en användarcentrerad utvecklingsmodell, analys - design - utvärdering - återkoppling, och en iteration har genomförts.Som utgångspunkt, för att öka användbarheten i webbplatsens gränssnitt, användes diverse regler och riktlinjer för hur användbarhet bäst kan uppnås, när designen gjordes. Hur väl dessa regler och riktlinjer fungerat tillsammans, i detta projekt och design, blev således en del i think-aloud testest utvärdering.

Införande av evidensbaserade metoder: ett kommunperspektiv

This thesis is composed within the framework of the supplementary course in psychotherapy concentrating on family therapy (60 credits) arranged by Lund University's affiliate in Västerås, Sweden.The purpose of this thesis has been to explore how the idea to initiate evidence based methods in the workings of the Individual and Family Care Department of the City of Västerås was born. Furthermore the thesis will explore if consideration for methods of theoretical implementation are implied. The study assumes a qualitative attempt and is based on semi-structured interviews from three levels within the organization, including both management and operation.Theories on organization,implementation and the theory on change strategies have been used as a theoretical starting point.The study result shows that introduction of evidence based methods in the City of Västerås is based on the experiences of the organization regarding the need to develop and increase social services contributions to non-institutional care. Experiences from expensive transferrals to institutions which only occasionally produced satisfactory results were a contributing factor. New published research and a strong interest and desire inside the department to improve and change social services contributions have naturally been a positive influence for the development.

Beslutsmodell gällande finansieringsform samt intern prissättning av ett företags truckpark

To be competitive in the corporate climate of today it is important to have effective logistic activities. A common resource within the internal logistics is forklift trucks, which are used to lift and transport material. It becomes more and more important to decide whether to buy, lease or rent the forklifts to obtain an optimal economic situation. Many companies have issues with internal pricing. It is difficult to price products and services correctly. It is common to price the overall instead of what it really costs.The purpose of the thesis is to present a model for the acquisition of forklifts for internal logistic operations, regarding financing and internal pricing, to obtain economic effectiveness and an optimal forklift fleet size. The study focused on a specific research question, and for this purpose interviews with experts were held, observations were made and a literature study was done.

Uppvärmningssystem : Ekonomi, miljö och drift

This bachelor thesis aims at investigate how a specified house can optimize its energy consumption.Today the house often stands for the major part of the energy consumption in a consumers? life,whereas an energy optimization creates economic as well as environmental advantages. It is importantto make old houses more energy efficient, but putting high energy demands on new houses could beargued to be more important. The installations functions as both the heart and brain in a house, thusmaking it important to energy optimize these. Since the background describes the importance ofenergy efficiency and optimization in a house, the focus area of this report will be an investigation ofdifferent types of heating systems in order to be able to choose the one most suited for the house.Aspects considered when choosing the heating system was how economic the system is both inservice- and investment costs and how environmental and operational friendly the system is.Through literature reviews there were sufficient information gathered that served as a foundation whencomparing and choosing between the four systems - district heating, pellet-fired boiler, geothermalheating and solar heating.

Vilka faktorer påverkar tjänstemäns arbetstrivsel

Studien ämnade undersöka vilka faktorer som till störst del påverkade tjänstemäns arbetstrivsel. Genom att dela in sex faktorer i tre grupper kunde mer kunskap förvärvas om vilket område av individ, chef eller organisation som har störst inverkan på arbetstrivsel. Undersökningsdeltagarna bestod av 196 stycken kommunalarbetare som besvarade en enkät. Resultatet visade att faktorer kopplade till chef hade störst inverkan, därefter organisationsfaktorer och minst inverkan på arbetstrivsel hade individfaktorer. De enskilda faktorerna som påverkade trivsel mest var feedback och delaktighet.

Gymnasieelevers förståelse av enhetscirkeln och trigonometri : en undersökning av elevers förståelse av matematiska begrepp, samt vad lärarna anser att nyblivna matematikstudenter bör kunna när de kommer till högskola eller universitet

The aim of my study is to investigate how last year students in upper secondary schoolunderstand certain mathematical concepts, in particular the unit circle and its trigonometry.I have used intentional analysis to interpret student?s actions when they solve certain tasks onthe basis of a cognitive, situated and cultural context.Interviews with four university teachers in mathematics about the unit circle, trigonometry,and mathematical understanding, serve both as background for the study and as basis for adiscussion, where I relate students understanding to what the teachers want new students toknow about these concepts when they begin university studies in mathematics.The students were arranged in three groups with three students in each group. Each group waspresented with two tasks, one in which they were asked to calculate the cosine values for onepointed, one blunt and one straight angle, each located in a separate triangle. They were alsoasked to decide whether the points (0,71; 0,71) and d (1 2 , 3 2 ) are located on the unit circleor not.My conclusion is that students mainly have an operational conception of the unit circle andtrigonometry. The lack of structural conceptions result in difficulties in seeing connectionsbetween the concepts in unfamiliar situations.

Upplevelsen av utvecklingssamtal kopplat till motivation, rättvisa och kontext

Ett regelbundet återkommande utvecklingssamtal kräver organisationens resurser i form av medarbetarens och chefens tid, vilket gör att utvecklingssamtalen bör hålla hög kvalitet för att vara meningsfulla. Studien har genomförts med intervjuer på en myndighet där medarbetarnas och chefernas upplevelse av utvecklingssamtal har undersökts. Resultatet visar att myndighetens syfte med utvecklingssamtal är otydligt och att det är oklart var frågor som rör medarbetarens lön ska diskuteras. För att utvecklingssamtalen ska bli meningsfulla för såväl organisation som de anställda är tydliga mål och syften med utvecklingssamtalen av betydelse. Val av plats där utvecklingssamtalet äger rum bör noggrant planeras för att minska den negativa kontextens inverkan på samtalet.
