Vi lever i en värld av klimatförändringar där det ständigt söks efter lösningar för att minska utsläppen av växthusgaser. IMO har infört SEEMP:en med målet att reducera utsläppen från världshandelsflottan och därmed öka dess energieffektivitet. Med denna bakgrund har syftet varit att undersöka hur svenska tankrederier implementerat och tillämpat SEEMP:en samt kartlägga åsikter kring den. En kvalitativ metod har använts för att på djupet undersöka rederiernas tillvägagångssätt. Undersökningen omfattar fyra semistrukturerade intervjuer med totalt sex personer ifrån två rederier där både ombord- och landanställda finns representerade.

Problem statement: Nowadays, women have a greater place in literature, both as a writer but also the role of the book and that is why I have chosen to examine how educators reason about their use of literature in preschool to combat the stereotype of gender roles.Motivation: An earlier survey shows that women now have a greater place in the recently released children's literature and, therefore, it is interesting to see how educators see their work on countering gender patterns using picture books. It is also interesting to examine whether the female roles in the books are consistent with the research I've used.Approach: I chose to use qualitative interviews with teachers in two preschools and also examined the recently released children?s books they worked with.Results: The results of my survey shows that teachers thoughts about their work on combating gender pattern occurs on an individual plan and depend on how the teacher interprets the guidelines. My survey also shows that the gender roles in the newly released picture books are consistent with earlier research I?ve used.Conclusion: It is therefore important that educators are aware of how easily gender patterns are induced, it happens on a daily basis through words and expectations that educators have on children..

The maintenance phase within software projects is typically very expensive in terms of resources. The activities of this phase are largely focused around some form of modification of program code. This leads one to consider if there are alternative methods of code production that results in code that allows for less costly modifications. This thesis has its basis in a subset of those concepts which research has shown to provide more flexible code. Once this subset is established, connections are made between the concepts within the subset and claims of benefits provided by the use of Test Driven Development (TDD) methodology.

Because of the increasing trends in energy consumption and increased environmental awareness, greater focus has been placed on improvement and development of renewable energy sources. An already proven and accepted method is biogas production from anaerobic digestion at municipal wastewater treatment plants.In the waste water treatment process solid material and dissolved pollutants are separated from the water, forming a sludge. The sludge is separated from the process and stabilized during anaerobic digestion or aerobic aeration. Most often, mesophilic anaerobic digestion is used. Because of degradation by microorganisms, biogas with a high content of methane is formed during the digestion.

This master thesis sets out to compare the different public transport modes in Stockholm city.Both energy consumption and air pollution are compared. The chosen transport methods are car,bus and metro.Traditionally the rail industry has had environmental arguments as a strong competitiveadvantage when it comes to passenger transportation. However, in recent years the automotiveindustry has been getting more positive media attention regarding environmental issues, forexample Roger Kemp?s statement that the car is the most environmental friendly passengertransportation mode in the UK. This study will show the environmental advantages of railwaytraffic in cities.The energy sources of the world are not endless and the use of the different sources affects theenvironment in different ways.

Background and problem discussion: Sustainability reporting has recently risen in importance and a rising number of companies choose to issue voluntary stand-alone sustainability reports. Their non-regulated nature increases the opportunity for management to angle the information in these disclosures to their own advantage. Lately the focus has shifted from examining what kind of information is provided in environmental disclosures, to analyzing how the information is presented.Purpose: The purpose is to examine if managers in the energy sector use optimistic tone when issuing sustainability reports. The aim is to find out if the tone applied in environmental disclosures is in congruence with either the environmental or economic performance or if an excessively positive tone is being used to mislead readers.Limitations: This study is limited to information found in environmental disclosures from private companies in the energy sector, issued in 2012 or 2013. Environmental performance is defined as the amount of CO2e emissions and economic performance refers to annual company revenues.Methodology: The quantification of optimistic tone is conducted using a content analysis, relying on a pre-specified wordlist and a pilot study.

The aim of this paper is to clarify the importance of communication between parents and educators, as well as collaboration. The survey involves cooperation between parents and teachers in preschool and in the survey; it is the educators? role and approach that is made visible. The issues I answer with the help of the interviewed teachers in the paper are: In what ways considers the interviewed teachers that can create dialogues with parents about children's daily life and activities? How do you describe the interviewed teachers that they interact with parents in preschool and the various forms of collaboration describe the interviewed teachers that they use in preschool?What difficulties consider the interviewed teachers may apply when creating dialogues and cooperation with parents in preschool Using a qualitative research method, the questions have been answered in the paper..

Today most ice rinks in Sweden use secondary refrigeration systems with a solution of calcium chloride and water as secondary refrigerant. Due to the large amount of energy such a system uses more efficient systems would be desired.An earlier study concluded in the possibilities of using carbon dioxide as secondary refrigerant with copper tubes as the loops in the ice rink. Since then 3 ice rink refrigeration systems has been built with carbon dioxide in copper tubes. Excluding the ones being direct involved in those projects there is still very little knowledge about how these system works. This study has been made primarily with the aim of adding to the knowledge concerning availability and cost and secondary to look at possibilities for improvement.A comparison between systems with carbon dioxide, calcium chloride respective ammonium solved in water has been made by using Decision Matrix.

The purpose of this study was to examine the various influences and advertising in particular affecting travelers' choice of destination. Data collection was conducted through quantitative method in the form of a survey to identify how travelers choose a destination, and to what extent they are influenced by advertising. Interviewees were travelers who were in Stockholm's central station would be passed on to Arlanda. The results from this study indicate that underlying factors such as economy, security, seasonal and service in place. The results also show that advertising is an important factor in selecting the destination.

In this report a study is carried out with the aim to identify added values of EPC projects implemented in schools in order to increase the interest of EPC projects on the market. The report examines how the planned maintenance, supervision, maintenance and corrective maintenance is affected, how insurance premiums and terms are affected, the indoor environment and how the tasks of the operating staff is changing. A literature study of energy savings, energy use in schools, maintenance and insurance as well as how energy efficiency improvements are related to the Swedish environmental objectives has been made. Visits were carried out in Ludvika, interviews were also carried out with operation technicians and local strategists in Ludvika as well as employees of insurance companies.Schools often have neglected maintenance and problems with ventilation and indoor environment. Schools also have a large energy saving potential due to their low utilization, mainly because they are empty parts of the year.

This study aims to explain how teachers for students aged 11-13 years old work with comprehension of words, based on reading fictional texts. The question formulations the study aims to survey is how teachers declare they are working with word-comprehension with basis in fictional texts for bothfirst- and second language learners, and how this shows in their pedagogical practice. The study also aims to survey what the effects are on the students´ learning, according to the teachers, by using this teaching-methods. In an attempt to examine this, interviews have been performed with three teachers working at different schools, teaching Swedish for students in the elementary school. In the interviews the teachers was asked questions in aim to research their methods of teaching wordcomprehension, followed up by two lesson-observations per class of each teachers´ pedagogical practice..

Swedish students' knowledge of mathematics has deteriorated in recent years. Teaching of mathematics is therefore starting point in an ongoing discussion among researchers, school leaders, politicians, teachers and others, who all thinks they know best about how teaching should be designed to the greatest extent possible to raise students' proficiency levels in the subject. Teachers' practices have long been the focus of discussions and views on these differ. The purpose of this paper is therefore to study students 'conceptions of mathematics and mathematics teaching, with teachers' methods and tools of focus, in relation to previous research on the subject. The method used was a survey of students in secondary school and a textual analysis of previous studies on the subject.As revealed by the survey was that the textbook has a big advantage in mathematics education in Sweden today.Many students are not accustomed to working in a different way and thereforedoes not know either what the alternative approach entails.

We have chosen to focus this paper on the importance of game-components in the MMORPG-game World of Warcraft, in order to discover which of them who are the most important and create the biggest motivation to play the game for the players of World of Warcraft. We made this  investigation because we wanted to find out more about the specific reasons about what people think is especially great with World of Warcraft and makes them want to play it for hour after hour. By doing this we wanted to find out what it is that is so appreciated with this game. But this is a big area and it has therefore been difficult to find a way to satisfy and make those who have answered on our survey to feel that the game-component they enjoy most has been a part of our questions.To solve this problem we did a survey that included 200 persons and two interviews. When both the survey and the interviews had been completed, the result was being compared against each other and together to see if there was any difference between them or if they had any similarity to the attraction and motivation.

Hur studenter klarar sina introduktionskurser i fysik på universitetet beror till stor del på deras attityder till fysik och fysikundervisning. Studenternas attityd påverkar hur dem arbetar med föreläsningar, lektioner, laborationer och kurslitteratur, och avgör hur studenterna gör för att tolka, resonera och bygga förståelse kring kursinnehållet. Det finns utförliga studier gjorda om vilka attityder som är fördelaktiga för fysikstudier på universitetsnivå. Men det finns väldigt lite forskning som visar om det är elever med fördelaktiga attityder som söker sig till fysikutbildningar. I detta arbete undersöks och karaktäriseras ett samband mellan elevers fysikattityder och deras val av framtida studier..

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.
