In this thesis, a computer program that in a simple way can calculate the performance of control loops at the refinery Preemraff Lysekil has been created. The computer program has been adapted to the environment at Preemraff Lysekil. Theories for evaluation has been studied in aspect of reliability and of automatic implementation. The evaluation has been carried out from data collected directly from control loops at the refinery and from simulated control loops with implemented errors. Among the studied methods are Harris index and Stattin´s oscillation index.

Powdery mildew is a serious problem in both field and greenhouse cucumber production and can cause serious infection and radically reduced yields. Today, powdery mildew is the main disease in greenhouse produced cucumber. Disease control should preferably be both efficient and environmentally friendly, which is not easy to achieve at all times. Alternatives to chemical control of powdery mildews are biological control, physical control, non-fungicide control and cultivation of resistant or tolerant varieties. Biological control can be described as the suppression of damaging activities inflicted of a harmful organism by one or more other organisms, which are called antagonists or natural enemies. In Sweden, there are currently no registered biological control products available to control cucumber powdery mildew. The aim of this study was to investigate the effect of two biological control products in order to evaluate their ability to prevent or reduce powdery mildew infection to an acceptable level in greenhouse produced cucumber. In the experiments, different application regimes were also studied.

Mergers and acquisitions are common phenomenon in today´s society in order to increase shareholder value. Two years ago a fusion of Sweden´s two largest companies in the industry of real estate took place and even though three out of four mergers and acquisitions financially fail this certain case turned out highly successful. The aim of this thesis is to examine how the organizational structure and the management control have been designed and characterized the organizational performance and furthermore what are the success factors of the integration. By studying an acquisition and its potential effects on organizational structure and management control parallel to a model that describes the best practice guidelines for managers to successfully deliver value from their acquisitions, it can be shown that an acquisition has direct effects both on the acquirer and the acquired company and thus the new organizational structure. The main results, thus, is that through active leadership, increased specialization, and more decentralized and thus efficient management control a new organization has emerged consisting of the best features of two separate worlds..

Municipalities must establish budget annually but they are free to decide how the governance should be designed, this can lead to lack of consistency and measurability within and between municipalities. The purpose of this thesis was to present a proposal for a unified and more measurable financial structure of a municipality where this was lacking. In our theory we describe the issues of traditional management control and we introduce an alternative control with non-financial ratios included, called the Balanced Scorecard. In the empirical data it is investigated how the governance of a municipality could be designed, according to the respondents. In the analysis the information gathered to reach the answers to what are considered to be useful governance in municipality, are examined. In the conclusion, we design Balanced Scorecards with both financial and non-financial ratios to the councils of the municipality..

The impact of classroom enviroment with respect to learning.

The aim of this paper is to examine why Swedish teachers and multilingual secondary   school pupils think it is important to read fiction, how Swedish teachers work with fiction in the multicultural classroom and how they motivate their multilingual pupils to read more by adapting fiction to their capabilities and experiences. We have done interviews with four Swedish teachers and 12 multilingual pupils. The following questions are the starting point of this essay:Why do Swedish teachers and multilingual pupils think that it is important to read fiction?  ?How can the Swedish teachers in the multicultural classroom motivate their multilingual pupils to read more fiction?The result of this paper showed that both the Swedish teachers and the multilingual pupils thought it was important to read fiction because it partly gives themselves the opportunity to acquaint with other cultures and it helps them to improve their language. The teachers motivate their multilingual pupils by reading out loud, reading in groups and by minimizing language difficulties that may occur in the fiction.

Problem The culture sector is characterized by qualitative goals which raise questions such as how do you measure culture and what is ?good? culture? Both the goals and the measurements tend to result in subjective judgments, which according to the theory make result control inefficient. Yet, result control is frequently used in the culture sector; which leads up to our research question: What characterizes the problems of result control in the culture sector?Purpose The aim of this study is to make a survey of how the Gothenburg Opera works with result control and follow-up. By defining how it tackles the different problems, which could arise with result control in a non-profit organisation, we aim to map how the problems regarding result control are characterized in the Gothenburg Opera.

Abstract  The purpose of this essay was to study understandings, determine the meening of a good learning environment in the school class, and how teachers and principal can contribute to it. On the basis of existing research that says: the common attitudes and standpoints between the school management and the teachers, is fundamental in case a good learning environment will occur in the classroom, the study has analyzed if the principal?s and the teacher?s attitudes in this study, are the same. The study is based on four main questions:  What is a good learning environment, according to teachers, principal and existing research?  How can teachers and principal contribute to a good learning environment, according to teachers, principal and existing research?  Do the teacher?s and principal?s attitudes concerning what defines a good learning environment, agree?   Do the teacher?s and principal?s attitudes concerning how teachers and principal can contribute to a good learning environment, agree?  To reply to the purpose of the study, five qualitative interviews were made. The interviews were done with five teachers and one principal, working in the same school. Research and litterature of interest, has been read, and these are presented in this essay. The study result shows that the existing research gives a wide definition of what a good learning environment is, and how a teacher and principal can contribute to it.

Swedish as a second language and special education are two topics that have a lot in common. I have chosen to in my study look at something that is covered by the two subjects: Swedish as a second language education that is taking place in a group segregated from the class. I have interviewed students in preschool, grade one and grade two to learn details of their experience of the segregation. Finding out that it is mostly bad planning and trouble getting the schedule together that?s affecting the pupils in a negative way.

I have with this thesis sought to understand how chick lit could be useful in the classroom in the teaching of Swedish B-course in high school. Based on the model of critical literacy I am arguing that this genre would help to meet the objectives of the policy documents which, among other things, are to critically examine and analyze various types of texts.I have found that some of these texts could be used for analyzing and critically examine the ideological dimensions of texts and cultural heritage by the model of critical literacy, and also as a counterweight to the more traditional teaching of the canonical literature as a literary historical stuff that students should learn. I have also wanted to create a basis for discussions about literature in the classroom based on the chick lit genre. To do this I have, based on three themes and questions from the model of critical literacy, tried to focus on issues that might emerge from the ideological analysis and critical review. The model aims to deconstruct norms of society, and in the work of chick lit, I wanted to show how you could deconstruct norms around gender..

This essay aims to examine managers experiences of control at the workplace within the property sector, and how these experiences differ between female and male managers. This study is a qualitative single case study that intends to offer a deeper understanding of a unique case and uses an abductive method approach. The essay is based on two main theories, Foucault?s (2003) theory of control and the gender system of Hirdman (1988, 2001) and is supplemented by previous studies of the modern workplace. The study is based on eighteen semi-structured interviews that aims to capture the participants personal experiences regarding control at the modern workplace, and the norms, surveillance, hierarchies, and self-discipline that make up this control.

In this essay I examine if socio cultural theory is present for teachers when pupils and students are using computers in class, especially when using blogs as a tool for learning. The aim of the essay is also to examine if blogs among pupils in class can promote peer support, co-operation and reflective dialogue, and in that case in what way. The essay consists of two studies, one small interview study and one literature study.  The interview study is made with the qualitative method phenomenographic analysis, presenting four Swedish teachers who have much experience using blogs in education. The aim of the literature study where some national and international research studies of relevance are presented, is to broaden the perspective.The result of the interview study shows that a socio cultural theory is highly present among the teachers who already use blogs in education. In addition, those teachers experience that the blog in the classroom supports dialogue and co-operation among the pupils.  In contrast, the literature study shows that most teachers in Sweden who made their pupils work with computers in classroom seem to let their student work alone, without guiding them and without creating co-operation or dialogue in the classroom.

In order to be a good teacher according to preferences from outside the school area, there are many different voices to listen to. The different roles that are assigned for teachers are colliding with the latest research from the pedagogical institutions and therefore the role as a teacher of today is in a complex state of mind. Somewhere, between the traditional role of teaching and the moderating ideal image, reality is revealed in the ambivalent role of the teacher of today. In this pedagogical essay on advanced level we are focusing on obstacles that are hindering the moderating teacher?s role, to be fully developed in the classroom.

Our governing documents give teachers guidelines as to how to carry out their task in the classroom. To guide a learner requires knowledge, not only about the policy of our governing documents but also skills to see the connection between the teacher's task and its practical implementation. By studying learners' experiences of teaching contexts, I have been able to evaluate how the teaching methods live up to the intentions of the national governing documents in Sweden.My study is based partly on a survey that I completed and partly on the theory of Dialogicity. Here I saw clear connections between my informants' experiences of verbal exercises in the teaching and the theoretical background I have chosen for my study, Dialogicity. I have presented and analyzed the verbal exercises in four differentiated contexts.

The accounting scandals that have attracted attention in recent years have led to internal control becoming a more central part of business activity. Doubts about what firms actually do have increased, all caused by the attention of accounting scandals. To counter this, frameworks and laws evolved and gained a significant role in the organization and its surroundings. The aim of the present study is to find out how four companies in the Kristianstad region are working to ensure its internal control and how they work to minimize risk and reduce uncertainty. We have used a qualitative method and interviewed a person in a senior position in each company.
