In the year 1783 a fissure eruption from Laki in the southern part of Iceland produced a large amount of volcanic gases during a period of eight months. The volcanic gases and aerosols spread across the northern hem sphere due to ideal weather conditions and had a substantial impact on the environment, human health and also climate effects. This, so called dry fog, caused severe health problems, which led to death casualties, killing animals, crops and other vegetation. The consequence was a widespread famine which was aggravated by a hard and long winter in 1783/84. Analysis shows that the Icelandic volcanoes are the primary risk to produce dry fog that can affect Sweden.

The aim of this thesis was to use qualitative approaches to show how teachers in primary school reason on their way to meet and communicate with children who have ADHD (Attention-Deficit/Hyperactivity Disorder). Research questions of the study were as follows: How does teachers in primary school reason about their way to communicate with children with ADHD? Do the teachers use some specific methods or means of communication with students who have ADHD? Do the teachers reason about their way how to handle conflicts with students who have ADHD? I collected my empirical material through a qualitative interview method. My theoretical starting points were interaction theory and the socio-cultural perspective. I have used these theories to analyze my material.

The public health care sector has come under increasing pressure to cut down costs, maximize productivity and satisfy patients' needs during the 1990s and onwards. As a way of "getting more for less" quality management has been introduced. Originating in the private manufacturing industry, quality management has a strong focus on productivity and efficiency, aspects which are measured in quantitative terms. However, there are strong concerns that quality management is a means of speeding up the marketization of public health care by introducing core values much different from the ethic and medical norms that traditionally underpin health care organizations.This essay focuses on how quality management has been introduced to, and transformed by, public health care. A theoretical framework based on new institutionalism is constructed, and translation theories are used as a way of illustrating how the medical institutional environment, in fact, changes the concept of quality management.

There are several competing views on how to best utilize air power. Following his quantitative study of air power, Robert Pape developed a theory which focuses on undermining the target state's military strategy. According to Pape it is possible to explain the outcome as a result of military vulnerability. This essay seeks to determine if Pape's theory can predict the outcome of Operation Unified Protector. By using a mixed methods approach on four hypotheses, it will be determined if the operation was a successful case of coercion, if NATO acted according to Pape's model and whether this achieved the desired effects or not. The results reveal that the theory could not successfully predict the outcome of the conflict.

The aim of this essay was to gain a deeper understanding about how school employees interpret and practice school law regarding cyber-bullying that occurs between pupils on the internet. To examine this we used a qualitative method. We completed eight interviews with five teachers, one headmaster, one school welfare officer and one special educationist. These eight school employees were from four different high schools. In our interviews we found that the school employees thought it was difficult to define different concepts within the school law such as in association with the occupation and offensive behaviour which prohibits them from interpreting the school law in the same way.

Purpose of the thesis is to construct a tool for car wheel change. Car wheels can be heavy and hard to handle and therefore the company Movomech intends to develop a tool that makes wheel change easier. Movomech does not have any similar product and because of this the work was condition less.The intended users of the product is tire workshops and there for the work began with investigation of these. The reason of the investigation was to see how wheel change is done and how tire workshops are planed. The tire workshops? crew?s opinions were also considered and above all one important conclusion was made.

Control of a diesel engine equipped with Variable Geometry Turbine (VGT) and Exhaust Gas Recirculation (EGR) requires a multivariable control method. One problem is that the engine system is non-linear. Furthermore there are strong cross-connections between inputs and outputs and the inputs have alsoboundaries. To be able to manage these control problems, MPC has been used that is a multivariable method. The MPC-controller consists of an optimization problem and therefore MPC can find the optimum control signals in an easy way.

The purpose of this paper is to understand how different fractions of Sweden?s left wing (the Social democrats, the Communists, the Syndicalists and the Socialist party) framed the end of the Spanish Civil War and the defeat of the republicans.To answer the purpose four newspapers Arbetaren (syndicalist), Folkets Dagblad (Socialist party), Ny Dag (communist) and Socialdemokraten (social democratic) have been analyzed qualitatively. The thesis has focused on how the different ideologies have framed the war, how they framed the other labour organizations and themselves plus how they relate to information about the war during the period of February 1st1939 till April 5th1939.The analysis shows that the Social democrats and the Communists framed the war as a conflict between fascism and socialism, whereas the Syndicalists and the Socialist party framed the war as a socialistic revolution. Because each side had their own view, their opinions on what threatened a republican victory differed. The Social democrats were most concerned that a non-democratic movement would win the war and the Communists feared that fragmentation within the republicans would threaten their chances to win.

The aim of the study was to illustrate how care managers reflect and act in regards to self-determination and integrity when caring for residents over 65 years old who have a dementia diagnosis. Our main questions dealt with how care managers handle the right to self-determination and integrity when a person has dementia, to which extent the care managers listen to the person with dementia and how the care managers look upon the residents with dementia?s ability of self-determination. To find the answers to our questions, we interviewed ten care managers within the elderly care in Gothenburg, Sweden. We used qualitative interviews based on a semi-structured interview guide.

This study examines the organization of the village society in Benestad, in southern Sweden, during the period from 1886 to 1928. The study focuses on the commonly owned resources in the village and how the landowners there came together and shared the resources. By studying the records of the societies? meetings, and in particular the cases that concerns the common resources, a categorization has been done. The results of the study show that the landowners in Benestad shared pasture lands, milk carriage and other resources with one another. Overall, the village society had a strong organization with at least two yearly meetings about the commonly owned resources.

Over the period as a student at the Master's Program for Educational Leadership, I have learned thatsometimes the participants School?s management shows concern regarding the purpose of studyingat such a program. The curiosity of what that might devolve upon got me to immerse myself in theapproach to and attitude towards competence development within educational leadership.The essence of what I wanted to examine was how the students from the above mentioned Master'sProgram perceived the treatment they received from supervisors and colleagues and if it waspossible to explain the attitude that the participants in the study reported. I also wanted to examinewhat issues, related to competence development and leadership within the school system, highlightsthe treatment of participants in educational leadership.The results are based on questionnaires and interviews and are divided into four categories; thesupportive, the unaffected, the discouraged and finally a side category to explain how to handle thediscouraged?s lack of support.

This thesis is set out as a testing of the crosscutting cleavages theory on twocontemporary cases. The aim is to test the explanation process of the crosscutting theory applied to the political and social situations in Belgium and Switzerland and furthermore to examine potential conflicts in pluralistic states. Our main questionis: How can the crosscutting cleavages theory explain the different outcomes ofsocial coexistence, even with the states numerous similarities? We have examined the two federal states through their social divisions of language, region, religion and socio-economy. Our findings show that both Belgium and Switzerland possess divisions in the above mentioned variables, which in most cases are cumulative structured.

Chalmers University of Technology today have numerous computers which are never powereddown, at the same time there is a need for more computation power for researchers.Hence, we have investigated the possibility to use the computers for computing power andsecondly, if there is no work to be done, to put them into power saving mode.We have made a thorough study where we compared different distributing systems andin the end HTCondor was chosen as the best to implement. HTCondor is an excellent systemfor opportunistic use of computing power, i.e. make use of computers that no one elseis currently using. The system is used at several universities around the world with goodresults and would be excellent at Chalmers, where there is a need for such a system.Our implementation shows that HTCondor is well capable of handling unused computingpower. HTCondor can handle most file types that may be run on the system.

Rapid economic development and urbanization has led to an improved standard of living for the Chinese people. Meanwhile, a series of environmental problems have also appeared and smog, in particular, has caused the Chinese people to realize how serious the situation is. Smog has seriously affected normal economic activities and people's everyday lives, resulting in financial losses, increased mortality and disease. How to handle the smog becomes particularly important. The purpose of this study is to describe and discuss the underlying causes of two sources of pollution, particulate matter and sulfur dioxide, as well as what drives individuals' and firms' environmentally destructive behavior.
