Self-driving cars are soon to become a reality to the commercial market. A self-driving car does not have a human operator, which enables some interesting characteristics. The main benefits are considered to be:The number of accidents and traffic jams should be reduced.Enhanced comfort.Energy usage could be decreased while capacity could be increased.This study concerns the causes for improved energy efficiency. The reason for improved energy efficiency is mainly because of the variation in terms of acceleration, braking and distance holding are reduced. The vehicles are more intelligent and can work together as a unity.

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

The intension of this study is to investigate the interaction between teachers and social workers in two diffrent countys. The study is focused on how teachers act upon suspicions when there are children at risk and what kind of support the teacher gets from social workers. Another importent question is if the teachers know what kind of rules regarding to confidentiality and if it would be better for the pupils if there were no confidentiality.To get answers to my questions, i have interviewed teachers and social workers in both countys.In this study I assume that the power has three dimensions and that there are four levels of interaction.Due to the law about confidentiality the social worker has the power over the teachers. Because the law about confidentiality it is difficult for teachers and social workers to interact.If the teacher want help from social services, she or he must call the social worker because the social worker will not call the teacher. If the social worker want to help the teacher and give her advice, the social worker can do that without breaking confidentiality.

This study has a double purpose. First, it explores and maps out the use of quantitative key indicators in social performance reporting within a microfinance portfolio. This was done on behalf of Storebrand Asset Management, who would like to aggregate and report the social results of their microfinance investments to their customers. The study concludes that the extent of social reporting and types of indicators used varies, meaning that it is hard to aggregate data for use in further reporting. Thus, the work towards the goal of social reporting has only just begun.

The theoretical focus in this master is information retrieval (IR), and especially the part of IR that includes interactivity. This research is by some researchers called IIR. Our principal aim was to examine if search engines on the WWW are taking advantage of research results from IIR research. A way to do this is to look at the application of special features, in this case query expansion (QE) and relevance feedback (RF). Both these methods aim for a better matching of documents and the searchers information need.

The purpose of this thesis was to find out what experiences teachers have from using a class blog in teaching. What are the advantages and disadvantages by the use of blogs in education?I have used qualitative interviews with four teachers in grades 1 to 6 who have worked with a class blog in teaching between one and three years.The study has shown that teachers' experience is that the blog serves as motivation and promotes learning for many different pupils and that, together with other digital tools is more equal. The main benefits that teacher mention is the expanded concept of text that offers multiple forms of expression and the authentic reader, which makes it more real, important and meaningful. Other benefits that come up are that it helps students to see their learning and learn from and with each other.

This final thesis consists of an investigation of how suitable it is to vertically integrate forest in Swedish forest companies. Different strategies to obtain raw materials have been evaluated and the advantages and disadvantages have been weighted against each other. The investigations contain a number of interviews with represents from companies with different strategies and persons that in different ways have faced the question of issue. An account study of SCA´s forest ownership has also been performed. The benefits for a forest company to vertical integrate forest consist mainly of safety in delivery, control over the supply chain and company image.

The purpose of this thesis is to examine how social workers perceive the concept of knowledge within social services, particularly within children and youth services. Our goal is also to study the employer's expectations and demands on graduate social workers. The main questions we address in this thesis are; What knowledge is seen as useful by employers and graduate social workers working in social welfare offices? To what extent does university education bring useful knowledge to the work being done by social workers? What practical knowledge is there in the workplace for social workers to learn? When recruiting, what expectations does the employer have of graduate social workers? What challenges are there with recruiting a graduate social worker?We have interviewed six social workers and four employers in the social childcare division in different municipalities in Skåne region, Sweden. We have used epistemology in our analysis.

Organic agriculture is financially promoted in Sweden by special environmental support and as consumers we are all encouraged to buy organic food. At the same time scholars at the Swedish University of Agricultural Sciences claim that organic farming does not provide any environmental benefits. The main criticism is that organic farming has lower yields than conventional, which means that more land is needed to produce the same amount of food as in conventional farming, leading to deforestation and loss of biodiversity. As for climate change, the critics claim that the significantly higher productivity in conventional crop production compared to organic, releases surplus land, which could be used for bio-fuel production and thereby replace the fossil fuels. The critics also claim that organic farming causes higher nutrient leaching than conventional.

AbstractThe aim off this study is to research social workers´ knowledge, use, risks and possibilities of social media in their work with clients. Because today the society is using social media networks in daily life and social media has become a tool in social work as well. How does social media and social work cooperate? And how does social media effect social workers? For example the website Facebook has grown huge and many people use it everyday. Where is the line between work and private life? To reach this knowledge in this study, qualitative interviews have been done with six social workers that work with children, youths and families.

The subject singing in elementary school changed its name to music in 1955 and with the name change followed a change in the content of the topic. In my study, I examine the perspective of how song as a subjekt has changed in the basic school curriculum texts. As a complement to text analysis, I used interviews in which two music teachers with long service in primary school were interviewed. My survey shows that there has been a clear change of the contents of concept song from being a pure skill where the aim was the vocal line benefits in different contexts and is today a vocal expression that can be embodied in many different ways. Curriculum texts have not been crucial to the changing content of the concept song.

The main purpose of this study was to examine own and social influence on perfectionismwith individual athletes. The participants (n= 96) of this study represented ten different sportsand their ages was between 15 and 44. An interview with four of the participant wasconducted. The instruments used for this study was the Positive and Negative PerfectionismScale (Terry-Short et al., 1995) and for the interviews questions was based on own and socialinfluence. The results showed that there was a relationship between positive perfectionismand own influence, negative perfectionism and own influence, negative perfectionism andsocial influence.

Today the school is a given place for preventing social problems. The school struggles continuously to live up to the expectations of balancing preventive social work with pedagogy in a satisfactory way.The purpose of this essay is to get a picture of priorities of social work in school. I want to know what it is that affects and controls the principal's decision about what kind of social project they will accept and be a part of.This essay shows that only one of the eleven principals interviewed apply projects based on evidence when they decide about participation in a social project. Instead, the decisions are based on references from other schools. The reason why the principals do not base their judgement on projects which are based on evidence is because they consider the search for results too time consuming.When there is no requirement that a certain part of the social work in a school must be based on evidence, it leads to the children taking part in different social projects which we can not guarantee are good for them.One solution can be to guide the principals through a national social teachingplan, which can assure that social work based on evidence are being applied in the municipality schools as well as the independent schools..

This document is a summary of my work to create a project management system for a small firm working with computer graphics. The intention is to manage customers, projects, images and invoices in the easiest possible way. To make the system as flexible as possible a web-interface was chosen which makes it possible to access the system from any computer, making it independent of any particular operating system. The only requirement on the user environment is that the computer must have a connection to the Internet to be able to access the system. The different techniques that have been used to develop the project management system is primarily Ruby on Rails and a MySQL database. Although Ruby on Rails was completely new to me, I decided to use this framework instead of PHP, which I already have a good knowledge of, because of the benefits Ruby on Rails provide.
