Kriterierna som ligger till grund för framgång för virtuella communitiesvill vi applicera på mobila communities. För att undersöka dessa kriterier, och bakomliggande faktorer, har vi valt att titta på ?tidigt bruk? användning av en mobil community, Facebooks mobila portal med hjälp av Technology Acceptance Model (TAM).

In this report the two authors, and project contributors alike, describe their work withdeveloping a solar cooker intended for usage in the developing countries of the world.Specifically, the work aims at developing a new, solar heat driven cooking device, possiblybased upon the current product. This should, in comparison to the current product, be lighter,easier to transport and to produce. Also, the new product?s production mustn?t be more costlythan today and the included materials and components must be obtainable from within theBolivian national borders where the product is currently produced. During the project, certainadvantages with a more efficient, and, above all, a more moderately priced product, werediscovered.

This paper explores the theoretical and practical uses and limitations of battle-field archaeology. The author aims to paint a big picture of the subject of exca-vating, understanding and theorising about historical battlefields done every day by archaeologists. Its approach places much weight on a quantity of examples rather than exploring specific excavations in every detail, in an effort to give the reader an understanding about how battlefield archaeology works. It stresses the need for battlefield archaeology as a way of obtaining and securing impor-tant archaeological and historical information before it is lost to science. The author tries to evaluate the subject in a critical and pragmatic fashion in order to establish a clear understanding about the facts of battlefield archaeology..

This study examines the cultural factors which necessitated the establishment of The Music Archives of Småland in 1991 in the city of Växjö. I wanted to know the importance of the local music tradition and the role of those people who worked to create an institution such as this. In order to do this I interviewed the chief collector of early folk music, Magnus Gustafsson, and made use of literary sources to devise questions and evaluate the results of the exercise. In this study I have made use of a model of a musical culture in a society, created by Lundberg and Ternhag, based on the theory of cultural fields by Pierre Bourdieu. According to this model, the stature of a musical culture gives different forms of musical expression certain roles, but these roles can be remodelled, reflecting perhaps political or ideological influence.

The purpose of this thesis work is to evaluate how the physical behaviour of a pipe bend is affected by the pipe bending procedure. Effects such as initial ovalization, thinning, thickening and plastic hardening from the bending procedure are examined and the mechanical properties of pipe bends containing these effects are investigated.This has been evaluated by creating a detailed Finite Element model of a pipe that is being bent. Then the differences compared to a bent tube in a virgin state, so called Elbow elements and an analytical in-house program have been evaluated. The virgin state refers to a model of a pipe that is bent from the beginning, thus having a homogeneous thickness and not containing any plastic hardening. The Elbow element is a calculationally cheap element, specially developed for accurate calculations of pipe bends in an initially virgin state.The goal with the thesis work is to get a better picture of what happens to a pipe as it is being bent, how this affects the mechanical properties and to evaluate the possibility to develop an easy method for taking these effects into account when using the Elbow element.This report describes the layout of the work and how the detailed FE-model has been constructed.

This essay focuses on the technical systems and functions behind how a Roman bath operated. I will present a general view by going through each part of the waters path through the bath one by one. Since there is no such thing as a standardised Roman bath I will, under each headline, present the sub subject with a presentation of the workings and then exemplifying through archaeological findings and ancient literary sources.This essay is therefore meant to present a thorough and clear presentation of the technical aspects of a roman bath. The aim is to give the reader an understanding of how a bathhouse worked in general and why. To this I want to present problems that the Romans were faced with and how they solved them..

SummaryThe purpose of this thesis is to examine what effect the IFRS 2 has on earnings, equity, financial strength and return on equity for listed Swedish companies with active stock option plans. The purpose is further to investigate the companies? attitudes towards IFRS 2 and to find out if companies tend to deviate from stock option plans due to the changed accounting rules. We also want to examine the view of IFRS 2 from an auditor?s perspective.We have used a deductive approach and a mix of quantitative and qualitative research methods with a view to get a completely clear picture within the field of study.

In today's society, the internet is an important part of everyday life. Over recent years the number of electronic services has increased markedly. Communities such as Facebook, consume more of people's time than 5-10 years ago. How can public authorities benefit from these communities or are the municipalities not ready for this? The municipalities determine how their resources should be allocated based on the municipality's needs.

The purpose of this study is from a case study develop a model that aims to cost effectively improve productivity in a manufacturing production process. The study highlights the importance of having knowledge about customer needs and using a holistic process perspective when improving productivity to identify the relations between the process stations and by this find problems that cause waste and losses in productivity. Tools and methods used to make production more efficient such as single minute exchange of die, spaghetti diagram, 5s and master production schedule is presented an applied in the model to see how these effect costs, productivity etc.Maintenance effects on quality and productivity in a manufacturing company will as well be covered in this thesis. The results and conclusions finally reveals how the process improvement tools, maintenance and production planning for example effects each other and why it is important to establish an attitude in the company where continuous process improvement should be emphasized..

Background: Businesses are traditionally valued with the so called Discounted Cash Flow-model. When valuing newly-started businesses, surrounded by high uncertainty, and whose capital mostly consists of unrealized business opportunities, the Discounted Cash Flow-model needs to be complemented if the total value of the business is to be captured. A valuation with the help of real options is capable of valuing these unrealized opportunities, which often exist in newly-started businesses. The unrealized opportunities are to be found in the business plan of the business, why this needs to be valued to capture the total value of a newly-started business. Purpose: To demonstrate what the use of real options can result in when valuing businesses.

AbstractObstacles or opportunities? ? A study of the experience of collaboration of social welfare secretaries and school staff.The purpose of this study is to illustrate the importance of the work with children and youth through the joint efforts between different authorities. The study deals with the collaboration between the social services and schools in the Ludvika municipality. The objective of the study is to investigate how teaching personnel and headmasters in compulsory schools and the social welfare secretaries in Ludvika, experience the collaboration, and how this works. On the basis of the objective, we have formulated some relevant questions; To what degree are schools aware of the model of collaboration, which is the basis for collaboration within the municipality, and are there any differences in awareness between different categories of employees? Other questions deal with differences in how the social services and schools experience the collaboration, discrepancies between different schools in this regard and if the respondents? experience any obstacles and/or opportunities by the collaboration.Collaboration is, and has been, a pressing issue for a long time in the public debate.

The purpose of this bachelor's thesis is to examine the information needs and behavior of Swedish theater students. The aim is to get an increased insight into how theater students search and use information as they create their character roles and also to examine how the information seeking is integrated in the creative process. The findings of this study have been made through qualitative data gathered from five interviews with six theater students who are studying at the Swedish Theater Academy. These students studied between autumn term of 2014 and spring term of 2015. To analyze the result of the interviews four different theories? have been used, Carol Kuhlthau?s information search process model, Lars Höglund and Olle Perssons model of four domains, Lars Höglund and Olle Perssons information search barriers and Tom Wilson?s model of information behavior.

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

This essay recognizes and criticizes a commonly held assumption that Corporate Social Responsibility (CSR) functions as a ?savings account of trust? between corporations and consumers. Based on five focus group interviews, the authors discuss how corporations that engage in society can sometimes raise and sometimes destroy the trust of potential consumers. One of our main findings is that CSR seems to raise the expectations among consumers. We then compare this phenomenon with the classical theory of the disconfirmation paradigm.

In this thesis I discuss and analyze different factors, and different circumstances, that influence identity negotiation among the north american indians. I do this mainly by using two models.The first one is Druckmans three dimensions of identity; negotiating identity, durability of identity and spread of identity. Depending on how the identity fits in these dimensions one can se if, or how, they influence the negotiability.My second model for analyzing is Reeds ?fasteing and unfastening identity?, using this model I have tried to understand during what circumstances the identity is negotiable. The identity is more or less negotiable depending on where the indians live, who they are living with and also on their inheritance.My results shows that the indian identity is changing and developing over time but the main characteristics still remains the same.
