Phosphorus (P) is an essential nutrient but a surplus could lead to eutrophication. Furthermore, the minerals used to produce the mineral phosphate is a non renewable resource. There are in other words several reasons to reduce the leakage of P and the agriculture is one important area to attend. The aim of this work has been to investigate if carbon-rich arable soils content contain more P than arable soils with low carbon content. Moreover it has been calculated if the carbon-rich soils could pose a risk of P leakage by comparing their delivery of P with the plant uptake. The work has consisted of compiling the results from former gathered and analysed soil samples of 130 Swedish arable soils. The fractions of P considered are water soluble P (Pw), ammonium lactate-extractable P (P-AL), hydrochloric acid-soluble P (P-HCl), organic ammonium lactate-extractable P (Porg-AL) and inorganic ammonium lactate-extractable P (Porg-HCl).

Bakgrund och problem: Vi upplever idag en världsomfattande ekonomisk kris med fallandetillväxt, minskad konsumtion och kreditåtstramningar. För knappt två år sedan var läget detmotsatta och de flesta av världens större börser nådde sin topp. Företag behöver oavsettkonjunkturläge finansiera sin verksamhet, i många fall räcker inte interna medel utan externtkapital behövs. Företagens val av kapitalstruktur kan i goda tider öka avkastningen men kan isämre tider orsaka stora problem som kan leda till konkurs.Vid val av finansieringspolitik i ettföretag måste vissa avvägningar göras. Ett av de mest väsentliga valen som företagsledningenmåste ta ställning till är storleken på skuldsättningsgrad som i sin tur styrs av mål förräntabilitet på eget kapital och i vilken utsträckning man är villig att ta risker.Syfte: Den här undersökningen syftar till att undersöka om det finns några samband mellanden finansiella risken i de undersökta företagen och storlek, tillväxt och lönsamhet.

The increase in farmland value in Swedens plain areas is a well known fact in today's Swedish agricultural. In connection with the fluctuating prices of crops and inputs, are increasing the risk exposure to agriculture. The increased value of agricultural land has in Sweden over the years been due to a high demand for land that has existed and exists in Sweden. The increasing demand is linked to a structural rationalization of Swedish agriculture, leading to fewer and larger farm units (www, privataaffärer, Carl Johan Jurss).The purpose of this study is to examine the potential risks associated with the farmland value falls or remains unchanged, according to a farm credit administrator's perspective. The idea is to get a picture of the main factors taken into account when lending and the problems with falling or stable land prices into account when lending.

Det finns faktorer på arbetet som påverkar yrkesverksamma till att bli mer eller mindre stressade. Socialt arbete inom socialtjänsten präglas ofta av en hög arbetsbelastning, höga krav, orealistiska förväntningar och i allmänhet ett komplext arbete. Det är något som påverkar hur den enskilda socialarbetaren upplever stress. Studiens syfte är att undersöka risk- och skyddsfaktorer för yrkesrelaterad stress hos socialarbetare samt deras copingstrategier vid stress. Den valda metoden för studien är kvalitativa semistrukturerade intervjuer med fyra socialarbetare inom socialtjänsten.

Theories about exposure and risk-taking in an everyday environment show a connection between parental strategies, parent-child relationship and exposure on the Internet. In the present study, the Internet is presented as an everyday activity. Negative exposure is seen as an outcome of risk-taking. The purpose of the study was to examine in what way parental strategies together with the parent-child relationship were related to the teenagers? negative experiences on the Internet, which consisted of three categories: 1) Exposure to pornographic sites, 2) Exposure to upsetting and violent material, 3) Digital bullying.

Shareholder value has its origin in the American corporate governance system and has been the subject of great debate over the last few decades. The proponents claim that it creates economic efficiency while the critics argue that maximization of shareholder value jeopardizes the long term survival of companies. However, the debate in Sweden already seems to have forgotten the question of how embedded the ideology really is and what´s leading its way. This study show that shareholder value has developed and been established in Swedish companies between 1995 and 2005. The study has found evidence that suggests that the development can primarily be linked to board networks and international exposure.

SAMMANFATTNINGBakgrund:Det skulle vara värdefullt att ha ett riskbedömningsinstrument för att identifiera äldre patienter som är i risk för komplikationer efter kolorektal kirurgi.Syfte:Att undersöka förekomst av postoperativa komplikationer hos äldre kolorektalpatienter och om riskbedömningsinstrument eller andra faktorer kan förutse dessa.Metod:En prospektiv studie med kvantitativ ansats och deskriptiv design.Urvalskriterier var patienter, män och kvinnor, ? 70 år, elektiv kirurgi för kolorektaltumör. Datainsamling gjordes före kirurgi genom intervju med standardiserade frågeformulär och test. Journalgranskning genomfördes 30 dagar efter kirurgi.Resultat:Trettiosex procent av patienterna utvecklade någon form av komplikation. Vanligaste komplikationerna var sårinfektion och urinvägsinfektion.

This study aims to analyze the risks with building new households between railroads and shore, the focus of the study lays on Öbacka strand in Umeå municipality. The study also investigate if a land use conflict has taken place and how it was handled.The paper is based on different documents that was central for the work of planning the households and some interviews with operators that was highly involved with the planning of the area.The results shows that there is several risks with establishing new household between railroads and shores. Mainly because of the exposure of noise from the railways, though the risk for impact on the living environment for animals were low in this case there is a generally risk that it could get negative effects. It also a very important that the availability to the shore is secured. Planning in this type of area involves a great number of operators can easily cause a conflict due to the different perspectives on how the land should be used in the future, and also because of protecting different interests.

In my study I have chosen to examine the mathematics in children's free play and everyday situations, with focus on sorting and classification. The purpose of the study was to see how children express their mathematical knowledge. I have chosen to use a qualitative method in my examination, here I did observations in a children's group where the children were between three and six years old. I also did interviews with the teacher's on the department to see how they relate to the mathematics and how they formulate the department to achieve as good a learning environment as possible.The result shows that the teacher's approach is incredible important to the children's learning ability and that they are always present to challenge and discuss together with the children. The observation indicates that children use mathematics all the time in their everyday situations and that it is the interaction between individuals and environment that affects children's development. .

Syftet med denna uppsats har varit att undersöka storbankernas etiska fonder.

During their hospital stay demographic data was recorded, as well as pre-, intra-, and postoperative tests and risk factors. The patients answered a questionnaire regarding postoperative wound infections 30 days after surgery patients answered a questionnaire regarding infections.

AbstractPeople and organizations that network with one another have during the past decades, at a larger extent than before, replaced classical hierarchies. These networks have become increasingly important, as the globalisation has amplified the pressure for focused and flexibleorganizations. There is a risk of restraining the inventiveness of the firm and force customers and suppliers into cooperation by a too great commitment and dedication to the network. There are two sides to every penny, positive and negative aspects of networking.Concerning the negative approach to networking, there is relatively little theory present. The theory is regarded an emerging theory.

Over a long period of time, there has been a rich debate in the academic and financial world if active management can generate an excess return. Many experts say that the current active management strategies is nothing more than a money grab that produces large gains, for banks and investment firms, through high management fees while producing no excess value for the individuals buying their service. In short, an effective market makes it almost impossible for fund managers to produce value for their clients in the long run.No argument has only one side though, other experts say that active management has a role to play because not all investors are rational. This irrationality can lead to mispricing on financial assets in the marketplace and in turn lead to an ineffective market where active management can fill a much needed role. The purpose of this study is therefore to see if active management strategies can create a higher risk adjusted return, taking management fees into consideration, during times of high volatility when the uncertainty is at its peak.
