In 1997, the Swedish parliament adopted a decision on Vision Zero (nollvision) in the road and transport system. Vision Zero means that no one should be killed or seriously injured in traffic accidents in the road transport system (Prop. 2003/04: 160). For the Transport Administration in Sweden (Trafikverket), this means increased demands on security and signage at road work sites around the country. This in turn means increased demands on the contractors that carry out road work for the Transport Administration.

This study where designed to investigate if there are any positive relationship between the extent of physical activity during adolescent's leisure time and the academic performance, and also if there are any negative relationship between the academic performance and the time spent in front of the television or computers. Another part of the study tried to find out if physical activity has a direct and immediate influence on the performance in school. 91 pupils (51 girls and 40 boys) in the 8:th year of the Swedish primary school, from three different schools participated in the study. All 91 pupils first responded to a questionnaire concerning there activities in leisure time. They where then tested in a mathematical test and the results where compared with the extent of physical activity and TV/computer time they had stated in the questionnaire.

The aim of this study is to examine which factors in a traffic wardens? situation at work that promote and which that inhibit satisfaction at work. The aim of this study is also to examine if there are any differences in the work experiences for traffic wardens that work alone versus those who work in a team of two. The following questions are examined in the study:?Which factors promote and which factors inhibit the work situation for traffic wardens??Are there any differences between traffic wardens that work alone and those who work with another colleague?The selection consisted of eight traffic wardens, of which four of them work with another colleague while the other four work by themselves.

The construction industry develops at a high pace today. Because of this the construction companies has to rethink and try to develop at the same pace. One of the biggest challenges in the construction industry today is to improve the logistics since improved logistics leads to lower costs. This is something that the construction companies have started to realize and they are beginning to invest more money in order to improve the logistics. It is especially important to have good logistics when the conjuncture turns for the worse.

The purpose of this work has been to understand the reading group from the perspective of the society. The studyhas taken place in the city of Västerås and the results can thus not be used in a more generalized sence. Byfocusstudies conducted with members from four different reading groups connected in different ways to the libraryin Västerås I have reached the following conclusions.According to Jürgen Habermas theories the reading groups, with their ideals regarding education and meetingswhere everybody are equals, belong in the part of the public sphere that he calls literary. There are someconnections to the political sphere, for exempel the down to earth quality of the literature that is the choice ofthe groups and their way of discussing it.One problem that occures when one tries to apply Habermas idéas regarding the public sphere on readinggroups is that the criteria Habermas considers as vital to sphere for it to work properly does not seem to workon the reading groups. Inclusion, eqality and freedom of subjects are necessary to create a public sphere.

The world is currently facing a huge severe challenge in handling the issue of climate change. One of the ways to lower the green house gas emissions, which is seen as one of the main contributor to the climate crisis, is to use renewable technologies such as for example photovoltaic (PV) systems. PV-systems are also suitable for so called micro production, small scale energy production facilities, since it can be placed on practically any rooftop with the right solar conditions. In Sweden the usage of PV-systems has not yet gotten any wider spreading, even though the solar radiation conditions are very similar to countries that produce a lot of solar energy, as for example Germany. The aim of this paper is to describe non-adopter perceptions of PV-systems. The study holds a qualitative approach using deep interviews for data collection.

What kind of self images characterise a football supporter? This question is the main focus of this thesis. Therefore, the thesis is trying to find distinguishing characteristic traits for football supporters. This work has been carried out through qualitative interviews with individuals who define themselves as football supporters. The interviews were mainly focused on two different types of supporters, official supporters and other supporters.

In Sweden there are about 4 million hectares of bare peat (mire). This land has great potential to be transformed into productive forest land, provided drainage is carried out and, in some cases, even fertilization with ashes. Drainage of mires is necessary because the high groundwater table prevents trees from growing due to reduced oxygen availability. Some of the key nutrients that trees need to grow appear in too small quantities in mires, especially potassium (K) and phosphorus (P). Ash from the combustion of biomass contains these elements and is therefore suitable as a fertilizer.

Modelling of pollutants is commonly used in research and at departments working with environmental issues. The need to use large amounts of data when modelling creates the opportunity for more generalised models with lower data demands. Aggregating functions into coarser elements is a sort of generalisation of actual features in nature.A development of a method and a modelling tool called ?KadmiumKalkylatorn? has been performed to model cadmium pollution in rivers in Skåne, Sweden. The water runoff has been multiplied with cadmium standard concentrations based on membership in landuse classes.

In 2010 mandatory audit was revoked for small and medium sized companies in Sweden. At the same time the authorization for accounting consultants was established with the aim of raising the knowledge and status of the profession. Even though The Swedish Companies Registration Office has discovered more errors in the accounting after the mandatory audit was eliminated, it especially concerns those companies who does not have neither an auditor or an accounting consultant. One of the reasons often mentioned to be audited is the auditors role when it comes to lending decisions. Our empirical studie show that the auditors most important function, being unbiased, is not what is of greatest importance for the credit institutions.Instead it was professional skills, and for small and medium enterprises (SME) it was consulting they requested the most.

In April 1986 an accident occurred at the nuclear power station in Chernobyl. Radionuclides were spread all over Europe including Sweden. Today there are still measurable concentrations of 137Cs in the different ecosystems in the contaminated parts of Sweden. The wild boar is the second most popular game in Sweden and today the Swedish population consumes more wild boar meat than ever. As the wild boar population increases the wild boars are moving further north towards the contaminated areas, which creates an interest to study the state of 137Cs in wild boars in these areas. Muscle samples from wild boars collected during 2010-2013 were analyzed based on 137Cs content.

The retrospective part of this study evaluates the susceptibility patterns of bacteria isolated from blood in critically ill foals in Sweden. The most commonly obtained bacteria were Actinobacillus spp. (38 %) and Escherichia coli (27 %). Trimethoprim-sulphonamide (TMS) had good efficacy against most gram negative bacteria with the exception of Klebsiella spp. Among 17 Escherichia coli isolates 94 % were susceptible to trimethoprim-sulphonamide whereas all 24 isolates of Actinobacillus spp.

Today there is a limited demand for quality certified cereal in Sweden. The demand can in the future increase and become a requirement for the entire market. Since the first of January 2005, grain producers in Sweden are food producers and traceability is important for the food industry. It is possible for grain producers to certify the productions under the certification IP SIGILL. The purpose of this essay is to explore why some grain producers continue to be certified while other producers end the IP SIGILL certification.

In previous studies there has been indications that multilingualism has a delaying effect of the onset of dementia and damage on cognitive abilities (Bialystok et al., 2007; De Bot & Makoni, 2005, s. 58). Cognitive abilities refers to memory, attention, language, abstract thinking and understandings among other things (Läkemedelsverket). Other studies have seen that individuals with Alzheimer's disease (Swedish abbreviation AS from here on) have difficulties with managing a conversation (Hyltenstam & Stroud 1989). This study aims to describe the topic treatment in bilingual individuals with AS and compare their different languages.
