Our planet is faced with enormous challenges as the extreme weather events related to the human-caused climate change continue to gain strength. The scale of the problem has made changing human behaviour the central focus of sustainable development, and both public and private sector are expected to gain relevant expertise and introduce this work in their agenda. Over its 40-year history, social marketing has become an established field providing tools for social change, but compared to health promotion, sustainability has not been a major focus of social marketing research so far. At the same time, sustainable lifestyles are embedded in complex systems where both individual factors and those of physical and social environment play a defining role in their adoption. Communities are a good example of such environments, and they became the key focus of Community-Based Social Marketing, which combines different insights from psychology to suggest a step-by-step framework for crafting behaviour change campaigns. However, it has not been applied to larger and diverse communities, like cities, and has not focused on sustaining new behaviour over time, which is crucial for creating sustainable lifestyles.

On ocean beds around the world sinking particles of residual biomass from animals and vegetation have, over time, accumulated into thick layers of sediment. For researchers these layers of sediment contain valuable information about the earth?s past climate, information that can be used to predict future climate change and to estimate natural vs. human causes of today?s global warming.The Institute of Geosciences at Stockholm University studies sediment cores that have been acquired with an apparatus called piston corer.

The main purpose of this thesis has been to address the problem connected with conservation ofspecific objects in historic buildings that have a protected building status. The immaterial demandsand environmental concerns of a place of cultural significance are discussed as opposed to the welladaptedsetting of a museum, with regard to long-term preservation. In an authentic interior of acertain era, large-scale individual treatments of the objects that define it and regulations forconservation-related reasons, may not be considered a worth-while effort, as it is often the integrityof the environment as a whole that has been declared as significant. To investigate the relationshipbetween object and its context, a case study has been conducted by examination of the propertycalled ?Curmans villor?, located in the seaside community called Lysekil.

Sammanfattning Vårt examensarbete handlar om användandet av laborativ undervisning på gymnasiet. Syftet med vår rapport är att undersöka vad eleverna anser om att använda detta undervisningssätt inom matematiken på gymnasiet. I vår undersökning valde vi att använda oss av två olika undersökningsmetoder, en enkätundersökning och intervjuer. Enkätundersökningen gjorde vi dels för att få alla elevers synpunkter och en bred syn på deras kunskap om begreppet laborativ undervisning. Vi ville även veta vad de ansåg om laborativ undervisning i jämförelse med traditionell undervisning.

Title: Bottleneck management through materials administration Course:  4FE05EAuthors:  Mikael Karlsson and Johannes Mueller  Examiner: Helena ForslundKey words:  Bottleneck management, material management, process description, timber, proceduresPurpose:   The objective of this study is divided into three parts, all three parts of the purpose aim for the same goal. Namely, to improve the material management so that this enables the bottleneck in the planing mill to keep a continuous  flow, and thereby minimizing the risk for production stops at LB-Hus.  Part.  1:  Identify  and  analyze the material management  connected to  the planing mill  in order to identify problem areas.Part.2:  Identify  improvement potential  in the material management connected to the planing mill.  Part.3: Suggest improvements in the material management connected to the planing mill. Theoretical framework: Process mapping, inventory accounting, balance safety, inventory availability / service levels, safety stock and reorder point, forecasting and routine descriptions.Empirical foundation:  Interviews carried out at LB-House,  illustrated with the help of process maps and a description of each process.  Conclusions:  To work with  the  suggestions  given  and  to  follow  clear procedures  in  all  processes would  result in  a more  efficient  inventory management,  it would also present  a  solution  to  the problem regarding the planing mill being a bottle neck.Suggestions for further research: Review and map the information flow from demand to production start.

GE Healthcare operates in Uppsala (Sweden) and develops systems, equipments and medium to purify medical substances. Discussions with the local authority concerning planed far-reaching changes and upgrades of the biological process techniques for sewage management, aroused the question about revising the terms of permit for the activity. Therefore it seemed necessary to evaluate a newly installed biological process technique, which is the background of this thesis. The evaluated biological treatment process was built in 2003 and consists of a biological reactor filled with moving bed carriers with a high surface area for biological growth. At the time of the project the biological wastewater treatment plant consisted of a flow equalization facility and two following parallel biological processes; a biological reactor with moving bed carriers and a tower trickling filter.The aim of this thesis was to survey the function of the biological reactor with respect to the reduction of organic matter.

The background for this degree thesis is a need to replace the existing seal used to protect equipment containing secret or sensitive equipment used by Swedish Defence. The target design should satisfy both the need for tamper evidence and reduce Life Cycle Cost. In developing a new design for a seal, additional benefits such as improved logistics support and indication of attack methods such as heat and solvents have been considered.The lack of guiding principles for end users of seals became evident during the interviews. Major concerns for the future are education of users, information about actions if a seal is broken and user liability.The design work was divided into several phases. A feasibility study was performed including investigation of theory of labels, materials and possible technologies.

This thesis explores in which ways the portrayal of the event known as the Stockholm bloodbath has changed during the period 1869-1996. This is done through textbook analysis. In Sweden, history has been a school subject since the 17th century, and has throughout its history had a formative role in the Swedish school system. In the middle of the 19th century it was specifically stated that the aim was to help students nurture a sense of national pride and love of country. The aim of the study is to investigate how nationally loaded events have been portrayed in text books, as well as if and how the evolution of said textbooks reflect the evolution of the history subject as a whole.

In this thesis, we have analyzed the Swedish debate about whether to impose a national canon, and make it compulsory in school curricula. Cecilia Wikström, a Liberal MP in Sweden, made the suggestion in July 2006, and the focus of our analysis is the subsequent debate during July and August 2006. Our materials are polemical articles from three Swedish newspapers, which we have examined to find the main ideas and arguments behind the various standpoints. Three issues have been our main focus; first, we have analyzed which concepts of culture the various debaters have used, where we have seen a difference between an anthropological and an aesthetical concept, but, surprisingly, found that there isn?t a very strong correlation between an aesthetical concept of culture and being pro-canon, or between an anthropological concept of culture and being anti-canon.

The aim of this study is to investigate how and in which form students come in contact with practical applications in the upper secondary school course Chemistry B. The study is based upon the assumption that all learning is situated in a social environment. The theoretical framework is the design theory perspective, which entails an assumption that the pedagogical tools affect the knowledge content.The empiric materials in the study are collected through three methods: textbook analysis, classroom observations and questionnaires. Two groups of students and their teachers were observed during a section of the relevant course. The textbook analysis focuses upon the same course section in the textbooks of the two groups and compares these books with the relevant section in a third textbook.

En ökad textilkonsumtion har lett fram till en problematik kring miljöpåverkan på grund av den ökade mängden använda textilier som ska hanteras efter produkternas död. För att ta till vara på de dyrbara resurser som har använts för att skapa textila produkter, har intresset för återvinning av textila fibrer ökat. Forskningen inom återvinning av bomullsfibrer har däremot inte kommit tillräckligt långt för att produktion av återvunna fibrer av hög kvalité ska kunna göras storskalig. Detta speciellt eftersom problem med exempelvis blandfibrer och separerbarhet försvårar arbetet. Det finns förändringar som kan göras av modeföretag i produktutvecklingsfasen redan idag, vilka kan underlätta återvinningsprocessen och syftar till att skapa ett slutet system i framtiden.

 In light of the resent surge in globalization, and the heightened competition that follows as a result of this, there has been an increase in the importance that is placed into understanding buyer behaviour. This increase has been seen since the realization that by building strong customer relationships it is much easier to reach these through the marketing communications that are put in effect. There are also a number of upsides to enlisting the customers at an early stage in product development, such as creating greater value and a stronger sense of involvement.Röhnisch is therefore trying to show a genuine interest in supplying the costumers needs as they adapt and evolve. In order to accomplish this strive towards gaining a deeper understanding into the thoughts and attitudes that precedes the buying behaviour they conduct regular surveys. To complement this, the purpose of this paper will be to determine the actual preferences and buying behaviour of the market segment that Röhnisch has chosen for themselves, and while doing so, keeping an emphasis on loyalty.
