Spårelement i Sveriges jordbruksmark : flöden, trender och fältbalanser
Field balances based on supply and removal of trace elements from the topsoil have been calculatedfor farms specialized in crop, dairy and pig production in Sweden. Today's field balances have beencompared with the field balances of 1990 in order to examine if, and then how, the situation haschanged. Studied trace elements are arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu),mercury (Hg), manganese (Mn), nickel (Ni), lead (Pb) and zinc (Zn).The balance calculations show that the stores of Cu and Zn are depleted with an average rate of -15% and -6 % over a 100-years period on crop farms when only commercial fertilizers are being used.The concentrations of Hg and Pb tend to increase in the topsoil on crop farms with more than 3 % forHg and with 2 % for Pb in 100 years. There is today balance between supply and removal of the traceelements As, Cd, Cr, Mn and Ni. In the south of Sweden, on crop farms with sugar beets in the croprotation, one can see a decrease in the concentration of Cd in the top soil by -6 % over a period of100 years.
Marktäckande, lågväxt vegetation på ställverksmark : en biologisk bekämpningsmetod mot ogräs
Unwanted vegetation on the land of electric transforming stations is a problem, in the sense that it contributes to higher fire risks and also constitutes an obstacle for people performing maintenance operations at the station. Such unwanted vegetation is controlled using herbicides and mechanical measures. Since the use of herbicides implies environmental hazards, there is a need to find alternative ways of fighting the unwanted vegetation.
Investigation into suitable plants for ground cover, trials in the greenhouse, trials in the field, soil analyses and compilation of experiences from similar trials are parts of this work. The paper also contains analyses of possible environmental benefits and economical gains. There is also a final discussion of some proposals regarding alternative weed controlling methods.

Mansklubben inom företagsekonomisk utbildning - En fallstudie om varför så få kvinnor fördjupar sig inom finans
Gender balance within the business administration field at university level is an area that has gained increased attention in the last decade. As gender balance contributes positively to the scientific and educational achievements within all disciplines, many studies have tried to understand the decision-making processes of students when selecting a business specialisation. However, little attention has been devoted to the finance discipline although there is a remaining gender imbalance within the field at higher-level economic studies. This thesis was performed as a qualitative case study and is based on interviews with second-year bachelor students facing their choice of specialisation at the Stockholm School of Economics. Through an application of the Theory of Reasoned Action (TRA), this study aims to examine factors that influence female business students' intentions to choose a specialisation.
Friidrottsungdomars fysiska kapacitet över tid : En retrospektiv studie av intagningstesterna vid friidrottsgymnasiet i Växjö mellan åren 1982 ? 2009
Background: Today when leisure time is spent, spontaneous sports activities decrease, due to a more comfortable way of living and physical capacity among non active adolescents decreases. There for it´s interesting to see how the physical capacity level has changed over time among young people participating in organized leisure time sports.Studies around the world show that young people standing outside organized sport activities have tended to decrease their physical activity levels over the last few decades. Less leisure time is spent doing physical activity and sometimes gets put into context with increased time spent behind the computer or inactivity.Design: A retrospective study of the test results on physical capacity between 1982 and 2009 for students applying to Växjö track and field high school. A total of 635 students (15 years old) have done 11 physical tests during the years. Five of these tests, with enough participants (at least 100) and documentation over at least 10 years, were used in this study.Results: This study shows that young track and field athletes have maintained the same physical capacity from 1982 to 2009.
Utvärdering av Politiskt Bistånd : En fallstudie av ett politiskt biståndsprojekt i Laos
The findings in this case study are mainly based on material collected during a field trip with a fellow student to Laos in February-March 2005, which was sponsored by Sida through a Minor Field Study scholarship. The original interest was to study a political aid project (Governance and Administrative Reform Project Luang Prabang, GPAR LP) in a country like Laos with very complex preconditions such as one-party polity. In Laos my interest in evaluation of political aid grew mainly because I found out that the two donors in the project, Sida and the UNDP, had reached different conclusions in their respective evaluations of the project.The main interest in this thesis has been to study how donors have evaluated a political aid project. The study shows that Sida and UNDP used, what in the literature usually is referred to as, Conventional evaluation as methodology when they conducted their evaluations of GPAR LP. The study also shows that the main reason for the different points of view that are expressed in the evaluations depend on a lack of dialogue and consensus, regarding for the project crucial concepts, rather than choice of evaluation methodology.

Designriktlinjer för övervakningssystem
Design principles are usually used by interaction designers to help creating a user friendly design by making the designer think about the different aspects of the design. These design principles has been further developed since they emerged in the 1990s, and today they're often used in the field of interaction design. By using the design principles, bad design can be avoided and the frustration of the user reduced. Design patterns is described as structural and behavioral characteristics to improve the environment in user interface amongst other areas. These characteristics could make things easier to understand or improve their appearance, they make tools more usable.The purpose with this essay is to identify design guidelinesto be used by developers when designing surveillance systems.
Rekryteringsprocessen och sociala medier : Hur arbetar olika HR-funktioner i Sverige med sociala medier i rekryteringsprocessen
An increased use of social media has enabled a new arena for HR functions and the work with HR issues. Proponents are critical of this, as it can lead to ethical and legal dilemmas. So far the research on this area is limited. On this basis I found it interesting to study how social media is used in connection with the recruitment process. Those who will benefit from this study are primarily those dealing with recruitment, but also others working with HR issues.

???????????? ???? ??som?leder oss i triumf?? En exegetisk studie gällande vad Paulus avser för betydelse och funktion med sin metafor i 2 Korintierbrevet 2:14a.
AbstractIn this essay I examine the exegetical problems concerning the interpretation of the metaphor ???????????????? in 2 Corinthians 2:14.The regular idea of the metaphor is that the apostle Paul is using the picture of a Roman triumph to describe the apostle?s and his co-worker?s service for God. This includes that God is leading them into many sufferings finished off with a martyr death as the triumph was very painful for its prisoners and mostly ended with an execution. But since A.D 300 such an interpretation has been questioned. Scholars react primarily to the cruelty of it and ask if that really was Paul?s meaning.

Hybridlandskap : nya möjligheter för offentliga platser i staden
This project explores how artificial landscapes as parks and squares above ground can save space by using the vertical voids in urban environments and how they can create spatial and social as well as ecological qualities and connections.
Hybrid landscapes are a phenomenon of current interest within the field of architecture and urbanism. Architecture as surface, where facades and roofs become possible to tread, is a relatively recent occurence that has over the past few years become an increasingly common sight in architectural magazines and on international architecture exhibitions. Many of my selected reference projects have often been associated with sensational contemporary design trends generated by advanced computer software. But the phenomenon is also a result of other different currents of change that exist within today?s society, such as densified cities with a lack of open space, which is also expressed in architecture.
