Att kommunicera idéer och visualisera information i 3D :

In order to respond to a more complex community planning with increased cooperation and public participation, a common language and a common model to be used as a base for the communication process is needed. The thesis behind this dissertation for a master's degree is that a virtual 3D planning portal would respond to this need. Why and how are explained and described through studies of communication- and perception theory as well as technology and recent research. The introduction concludes that a broad participation and a transparence towards underlying information are important foundations for the coming work with the model. The first four chapters of the theory part show the benefits of using natural signs in our mixed cultural society, instead of the more arbitrary symbols. Using visual landscapes for storing information is motivated by the flexibility of our visual memory and its ability to understand complex connections.

CSR i sociala medier - Möjligheter och risker med att kommunicera CSR i sociala medier

This B.Sc. Thesis examines how Swedish Large Cap companies communicate CSR in social media. We describe the current state of CSR communication in four different social media channels, Twitter, Youtube, Facebook, and blogs. This research, supported by interviews with stakeholders and a quantitative survey, analyses the potential risks and benefits from communicating CSR via social media and provides concrete advice on the development of a CSR communication strategy for social media. Although some benefits have been realized, many companies have failed to truly reap the potential benefits from an effective social media strategy for CSR.

Samtal om texter för ökad läsförståelse : Introduktion av boksamtal i en F-3 skola

This study covers reading comprehension and the introduction of the "Tell me" approach as proposed by Chambers (1993) to a group of teachers in a Swedish F-3 school. Five teachers got to use the method for three weeks and were interviewed before and after the experiment to analyze their current ways of working and reactions to using the method in everyday tutoring. The result from the first interview showed that all of the participants had been using methods to improve the children?s reading comprehension prior to the study, but no one had tried the "Tell me" approach. After trying the method throughout the test period, all of the participants were positive about the methodology and showed an interest in continuing the use of it.

Mätning i nätstationer - nyttor och problem

The purpose of this study has been to investigate advantages and problems with distributionsystem metering in substations. This report is a study in cooperation with Göteborg Energi.The analyses in this report are made for GENAB, a subsidiary company of Göteborg Energi.To analyse advantages and problems in advance is interesting information for GENAB. Theresult of the report could be based upon whether installation of metering in distributionsubstations will be implemented and in that case which kind of measurement that is relevant.The most relevant and strategic place to implement measurement is at the distributionsubstations on the secondary side (400V), this is due to the placement of the currenttransformers. The measurements in this study involve current, voltage, power, power factor,temperature, energy and power quality.Measuring instruments that are relevant to implement are intended to measure current,voltage, power, power factor, energy and, possibly, power quality in the same measuring unit.It is desirable to have a measuring instrument that measures both energy and power qualitybut since it is most often a cost question, it can be established that energy meters have a lowercost.Metering in distribution substations gives a better illustration of the power network. Thisresults in many advantages for GENAB.

Fastighetsutveckling i Farsta. Ekonomisk analys av TeliaSonera-områdets framtid

Stockholm is one of the fastest growing cities in the world. Its population is growing every day and the housing needs are becoming higher. Despite the growth and the need for more houses only a few new housing units are being built every year. Critics argue that if the building rate stays as it is today the development of the city will be very limited since there is no capacity for the city to embrace new incomers.The decision makers in the municipality of Stockholm are planning for large investments in housing units for the coming years up until 2030. There are plans of building approximately 140 000 new apartments to mend the ascending need for new houses.Farsta County is part of Stockholm and lies a few kilometers to the south of the city center.

It then moves on to a thorough description of the buildings in question, and their heating- and ventilation-systems.Followed by this the reader is guided through the successive stages of energy-perseverance measures that are available, and possible. Reasoning around the economic factors concerning all measures is also held.The paper ends with conclusion, and a discussion concerning the delicate issue of the higher return-temperatures possibly reaching the district-heating plant..

Låt den sista utvägen bli den första ingången : Att underlätta implementeringen av ett nytt intranät då dess föregångare underutnyttjats av de tänkta användarna

The purpose of this thesis was to ease the implement of an upcoming intranet for a target group who had used the previous system to an unwanted low extent. After qualitative and quantitative studies I found that the users of the current intranet thought it was hard to navigate and did not understand neither the relevance of it in their own work nor knew which information it contained.Since I did not have access to the new system by the time of the making of this thesis I concentrated on rectifying possible problems with the new system regarding the relevance and the contained information. With basis in a number of theories I produced an information brochure, whose object was to inform about the content and to convince the target group of the relevance and utility of the new intranet. .
