Instant Messaging - Ur ett Media Richness Theory perspektiv
Under tidigt 80-tal växte olika sorter av kommunikationsmodeller fram, bland annat Daft och Lengels, Media Richness Theory. Denna teori var baserad på den tidens kommunikationsmönster. Idag nästan 20 år senare har vi sett explosionsartad IT-utveckling vilket har medfört förändringar i det dagliga kommunikationsmönstret. I denna uppsats undersöker vi om Media Richness Theory fungerar på ny teknik med hänsyn till dagens utökade kommunikationsmetoder. Vi studerar bland annat användnings- och påverkningsmönster ur ett abduktivt perspektiv, det vill säga både kvalitativt och kvantitativt.
Plastfilmsöppningar till Tetra Paks förpackningar : En teknisk introduktion och tidig konceptutveckling
This master thesis is an early concept development project about using plastic films and sheets as materials for shaping openings for Tetra Pak packages. It is also a technical introduction highlighting the areas of importance for the development of plastic film and sheets openings. The master thesis has been carried out as a co-operation between Chalmers University of Technology, KTH Royal Institute of Technology and Tetra Pak AB.The master thesis study presents an introduction that gives an understanding of the technical complexities and design possibilities of using thin plastic films and sheets in liquid carton openings. The knowledge is then transferred into five design concepts which points out the areas of opportunity. The technical introduction is widespread and extensive covering current packing trends, the liquid carton package and openings, thermoplastic material properties, and thin film and sheet manufacturing and shaping.
Projektledares motivation och metod : Med utgångspunkt från Vrooms förväntansteori
In today?s changing environment, creation of projects by organizations has become more common. The problem is, though, that the knowledge of the subject is still limited which causes many projects to fail. This has made it extra important to have a good project manager whocanlead the project in the right direction. While doing this both the project method and the project manager?s motivation are contributing sources.
Teknikundervisning för yngre barn? : Förskollärares, lärares och anställda i näringslivets attityder till Teknik och Teknikundervisning för barn i yngre åldrar
Syftet med denna studie är att uppmärksamma attityder till Teknik hos förskollärare, lärare, skolledare och näringslivsrepresentanter och försöka ta reda på tänkbara orsaker bakom dessa attityder för att se möjligheter och svårigheter i arbetet med ämnet. Den forskningsfråga jag kommer att försöka besvara lyder: ? Hur ser några ?tidigarelärare? förskollärare och representanter från näringslivet på barns tidiga möten med Teknik? De empiriska data som studien bygger på kommer från 83 enkäter och 2 intervjuer. Enkäterna besvarades av 28 förskollärare, 30 lärare och 25 anställda i näringslivet. Intervjuerna hölls med en person ur ledningen på ett större företag och en skolledare.

Humor i landskap : en introduktion till humor i landskapsarkitektur med fokus på Benign violation theory
Denna uppsats är tänkt som en introduktion till ämnet humor i landskapsarkitektur - ett ämne som ännu inte diskuterats i nämnvärd utsträckning. Den riktar ett särskilt fokus mot humorteorin Benign violation theory och undersöker om teorin kan användas i landskapsarkitektur.
Först introduceras de tre tidigaste humorteorierna för att ge en bild av tre huvudsakliga modeller som finns för att förklara humor. Därefter presenteras Benign violation theory och enkätundersökningen som prövar dess applicerbarhet på landskapsarkitektur. Undersökningens resultat verkar tyda på att bilder som stämmer överens med teorins villkor verkligen uppfattas som roliga, men det finns stora felmarginaler och det råder behov av fler undersökningar i ämnet..
Det moderna biblioteket inätverkssamhället : En studie över kulturpolitikers och bibliotekariers åsikter om bibliotekens användande av sociala medier
?The modern library in the network society?A study of cultural politicians and librarians opinions about libraries' use of social mediaSocial media is becoming more and more interacted in our daily lives and Carlsson (2013) argues that today's libraries have undergone major challenges in the digital information technology's entry in the library arena. The new technology has led to sum up in one question: how a library should relate to the digital information technology, the issue has applied in particular the social communications media, such as Facebook, Twitter and more. The purpose of this paper is to examine the culture of politicians and librarians 'perceptions of public libraries' use of social media linked to the libraries and their democracy promotion efforts. This is analyzed from Castells theories about the network society and the digital divide.In summary, the study concluded that the majority of the culture politicians and librarians believe that social media is a part of the future of the library.
Samverkansplanering : en jämförande studie mellan praktik och teori
Collaborative planning
? a comparative study of theory and practice
Why
There is today, according to my experience, a growing interest and
demand for a more inclusive and transparent planning process. Also,
if we are going to be able to reach a truly sustainable society it is my
belief that there is a need for a more integrated collaboration between
different actors. Where the social, economic and ecological values can
influence and benefit from each other. The question then is, how can
the planning system accommodate that kind of collaboration?
Purpose
My aim for this thesis has been to study a selection of the theoretical
work that exist about collaborative planning.

Jämförelseförsök mellan ogräsharvning och radhackning :
The organic farmland is increasing all the time and the goal is that 15 % of the Swedish farmland will be in organic production in year 2010.
The organic production needs new and more effective ways to control weeds, and there is the row harrowing coming as a good complement to the conventional weed harrowing.
In this experiment is weed harrowing whit different row spaces and row harrowing with a spacing of 25 cm compared. Then are the weed picked and the weight taken of them. The yield is compared in the 7 different ways of treatment.
The results is not showing any significant differences in yield even when the row spacing is 25 cm instead of 12,5 cm. Even the spring wheat that is a sensitive crop and has bad tillering is doing well in this experiment.
Now with modern technology where the row harrow is controlled by a camera that making the row harrow to follow the rows is it the soil coverage of the crop that is the limit for the speed. With wide machinery is the very good coverage even with a row harrow..
Spoiler alert : En analys av kvinnliga karakta?rer i tv-serien Homeland ur ett nationsperspektiv
This essay is a comparison according to the ideological thoughts about womens position in the society of Mao Zedong och Josef Stalin. The material I have analysed is writings by Mao and Stalin, in a wide range from leaflets to orders to the armies of the states of China and the Soviet Union. The method I have used is an ideological analysis where the attitude towards women is the target for my survey. The attitude towards women generally was not unified in the world during the time for Mao and Stalin. In many countries the women was intended to take care of the children and the home, not be active in working and fighting.
Kunddriven tjänsteutveckling? - en kvalitativ studie av Scandinavian Airlines.
The deregulation during the last decade within the airline businesses have called upon a more fierce competition among airlines. This fact forces airlines to continuously focus on service development in order to offer attractive solutions to satisfy customers changing needs and stay competitive. This paper focuses on service development at Scandinavian Airlines. The aim of this case study is to examine the sources of information used in service development and new service development at Scandinavian Airlines. Further the aim is to examine whether information derived from customers can be shown to play a more important role in either service development or new service development.
Att splittra en hierarki : Applicering av poststrukturalistisk feministisk teori på SAB-systemet

The purpose is to study if it is possible to open up the current representation of gender towards a more multiple one. The study is both theoretical and empirical. The theoretical part include a short presentation of both classification theory and feminist theory. The study also presents the critic that poststructual feminists submit.
Optimering av OTEC-system
Ocean Thermal Energy Conversion, OTEC, is a sustainable energy conversion technology that is not yet commercialized. OTEC is a technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program for three alternative OTEC systems has been created in order to decide which OTEC system is most profitable; closed, open or hybrid system. In this simulation a production cost analysis is performed in order to investigate and decide which one of the three systems that has the lowest production cost. The production cost analysis also analyzes if the profitability is affected by the size of the facility. After these analyzes, the most profitable of the three different OTEC-systems is expanded by an installation of solar collectors in order to see if the thermal efficiency is improved. The result shows that the most profitable system varies with the size of the facility.
