The aim of this thesis is to study the possibility of the existence of a specialist in bone tools manufacturing during the Mesolithic. The thesis describes the climate during the Mesolithic, argues for an experimental approach, and describes social organization in hunter-gatherer-groups and the processes behind cultural transmission. It also gives some examples of excavation sites in Scandinavia. An experiment simulating a teaching situation is made, in addition to the theoretical information, with the intent to explore how advanced the crafting of bone really is. The physical result is then studied and documented.

With background in the acknowledgement of the current period of major change in the characteristics of traditional Swedish foreign policy, considering the membership in the European Union, as well as the new contextual scenarios that Sweden has been situated in after the end of the cold war, this thesis aims at scrutinizing the Swedish Foreign Policy from 1991 to 2010. The purpose of the thesis is further to localize continuity and change in the ideas which Sweden has explicitly stated in its foreign policy. Based on the theory of institutionalism, the thesis also aims to bring forward plausible explanations built on the main empirical findings. This has been done by identifying different types of goals and means within realism and liberalism as well as categorizing each theory within three ideal types.The chosen research method has been a qualitative text analysis with focus on an ideational analysis. The material on which the descriptive analysis is based upon is constituted by the annual statements of government policy in parliamentary debates on foreign affairs.The results of the thesis show that the ideas that are related to solidarity, consensus and active foreign policy are constant through the period of examination.

During the last years, enviromental issues has been higly topical and everyone is involved in the end.

I´ve also intervjued one tibetan munk whoes ben working as teacher and director. I´ve also studied a societyorgan that have a close realationship with most schools in the area.

Ocean Thermal Energy Conversion, OTEC, is a sustainable energy conversion technology that is not yet commercialized. OTEC is a technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program for three alternative OTEC systems has been created in order to decide which OTEC system is most profitable; closed, open or hybrid system. In this simulation a production cost analysis is performed in order to investigate and decide which one of the three systems that has the lowest production cost. The production cost analysis also analyzes if the profitability is affected by the size of the facility. After these analyzes, the most profitable of the three different OTEC-systems is expanded by an installation of solar collectors in order to see if the thermal efficiency is improved. The result shows that the most profitable system varies with the size of the facility.

Culture, orgin and identity are hot topics that are being discussed everywhere, for example in newspapers, lunchrooms and on Twitter. Politicians, media and ordinary people have displayed different antiracist acts, for example campaigns, marches and political actions.But you may wonder if it really is that effective, or if the antiracism reproduces racism with its language. The purpose of this study is to see if articles from the newspaper Aftonbladet's antiracist campaign ?We like different!? reproduces racism through its language.The method that is used is discourse analysis, more specific Chantal Laclau och Ernesto Mouffes discourse theory. The theories the study relies on are race, racism, framing, racism in news, binary oppositions, stereotypes, whiteness and orientalism.Two discourses were found in the material, ?We like different? and ?We like the same?.

The sea-level is rising due to climate change. This report inquires into the possibleconsequences of sea-level rise in Värmdö and its archipelago with particular focus on roadsand buildings. Four scenarios with a sea-level rise of 0.5, 1.5, 2.5 meter and a worst casescenario of 3.9 meter are analyzed using a geographic information system (GIS) calledarcMap. The report also examines how Värmdö is taking into account future sea-level rise intheir planning today. The report´s findings show that uplift and sea-level rise cancel eachother out in the scenario with a sea-level rise of 0.5 meter, but that a number of more or lessimportant roads and buildings will be affected by a rise of 1.5 meters.

This study has the purpose of looking at the current and future position of recordlabels from a context involving the technological developments, while theopportunities for the artists are changing. As the actors inside them music industryfind themselves in an ever changing climate where traditional supply chains arethreatened by new technology, the record labels need to change the way they workin order to maintain their existence in the music industry. The study has beenconducted by interviewing a number of people involved in the music industry, byusing a qualitative method approach. The conclusion of the study shows that thetraditional way of doing business by treating music as a product that makes revenueis gone. Instead the labels have to take on new roles formerly run by third parties inorder to survive and be profitable, especially since artists can now in control ofactivities that used to be controlled by the record label..

Purpose/Aim: To create a communication strategy for PADI Nordic with the intention of getting Swedish divers, who have been certified abroad, to Swedish dive centers.Material/Method: The study is based on a number of personal interviews conducted with a) divers who are active in Sweden, b) divers who are not active in Sweden and c) representatives from PADI and PADI affiliated dive centers.Main results: The main reason that people who have been certified abroad do not dive in Sweden is that they regard it as being too complicated, too cold, too expensive and with nothing interesting to see. These might partly be misconceptions that can be corrected through a communication strategic effort. The best way to change this perception is by two different forms of communication. One will go from PADI Nordic straight to the divers through an email. This will have the purpose of getting their attention, making diving sound interesting and raise their awareness in preparation for the other part of the process.

Moisture damage in kitchens is an area that many people believe to be irrelevant andnot a subject to concern, however the problems encountered might be larger thananticipated.The purpose of this essay is to get a view of how problematic moisture damagecurrently is as well as what can be done to prevent damage during the constructionand building of new housing.Statistics regarding moisture damage as well as several tools for damage preventionhave been studied and investigated. Industrial regulations have been reviewed tounderstand the requirements construction companies must legally follow during theconstruction and building of new kitchens. Home manufacturers and largerentrepreneurs have been contacted in order to get their point of view regarding theproblems with moisture damages in kitchens.The knowledge of moisture safe constructions is prevalent by home manufacturers,insurance companies and entrepreneurs. Despite this knowledge, the constructioncompanies predominately follow the industries regulations, which normally onlyimplement the minimum requirements.In order to get construction companies to design and build kitchens with increasedmoisture security, stricter industrial regulations might be needed to be implemented.Unlike bathrooms and laundry rooms, kitchens are not defined as a ?wet room? andthe regulations for the construction of kitchens are more lenient.It is difficult to detect water leaks in an early state and the moisture damage is usuallyextensive before it is discovered and repaired if the kitchen lacks moisture securedconstruction and water security.

The energy consumption continues to increase as the use of electronics and energy consuming equipment increases. The use of fossil fuels has to be phased out for this to be sustainable in the long run while the use of renewable energy continues to increase. A renewable energy source is solar energy but the production of heat and electricity are today very expensive compared to other energy sources and an important task for the solar energy market to grow is therefore to minimize the production cost of the solar collectors while increasing its efficiency to produce heat and/or electricity. One way to convert solar energy into heat is by using solar collectors and electricity can be produced by utilizing the produced heat, or by applying solar cells.This thesis aims to recommend a reflective material for the next generation solar collectors from Absolicon and to recommend a commercially available coating for the receiver tube of the solar collector. A market study has been carried out to investigate the cost-related aspects along with the optical and durable aspects for the optical material of the solar collector.

The cattle production in the world has been questioned in Sweden due to its negative impacts on the environment. The use of imported soya bean meal as a protein feed for Swedish cattle results in the cutting of rainforest and an extensive use of pesticides in the countries were the soya beans are produced. As a consequence, the environmental impacts caused by cattle production increases. A production of protein feeds in Sweden would decrease the transportations and the cutting of rainforest. For organic beef producers the possibility to produce home-grown protein feeds is important since organic protein feeds can be difficult to obtain in another way.

The essay discusses how to look at a equality plan of a academic department experiences the, gender equality in general and how power is portrayed from a gender perspective in the academic department. Through the use of qualitative interviews and a short survey the results have shown that few of the staff members have knowledge about the equality plan and few are familiar with its contents. Furthermore results show that the academic department is run hierarchyilly and that both vertical and horizontal gender segregation exists.The climate at the academic department is characterized by the will to work with gender equality but so far there have only been few exercised or planned efforts to do so. The gap between theory and practise is wide, the will to be seen as an equal academic department concerning equality of men and women seems important. The conscious or unconscious strategy of covering up the real gender equality seems to be done by focusing on the numerical equality..

Climate changing is a growing problem for many countries and communities over the world. The cities has a huge work to deal with in their reforcements of their cities to be resilient ones. This thesis makes an effort to investigate and illuminate some of the problem the cities has to solve related to flooding, hazards, erosions, rising sea levels and crotches. This thesis will help to find solutions that international and national efforts has produced and handed out to each other. A lot of communities are charing their excellent tools that works for them.

This essay discusses people's perception of what is important for their well-being where they live. The main aim has been to find out what factors in the outdoor environments of the city are appreciated and why they are valued positively. A comparison has been made between Uppsala in Sweden and Tarapoto in Peru to see if, and in that case what, differences can be found in the values of people. I chose to carry out a survey study that got a response rate of 57 persons in Tarapoto and 63 in Uppsala. The results show that there are some common basic values, but on the whole the outdoor environments are valued differently in the two cities. In short, the Peruvians value functionality, cleanliness, small distances to family and service, while the Swedes value a central location and short distances to friends apart from functionality and good service opportunities. Conceivable reasons for this might be for example different cultural prerequisits, material standard and climate. .
