SyfteSyftet med studien har varit att ta reda på hur ungdomars drogvanor när det gällercannabisanvändning ser ut, och ställa detta mot risk- och skyddsfaktorer som kan finnas i skolmiljön samt inom familjen för att utröna om det finns några samband mellan cannabisanvändning och ovan nämnda faktorer. Frågeställningarna är: Hur ser cannabis- användandet ut i förhållande till kön, årskurs och stadsdelsområde i Göteborg år 2010? Vilka samband kan vi se när det gäller cannabisanvändning i relation till de risk- och skyddsfaktorer kring skola (skolk, trivsel, betyg) och familj (positiv uppskattning, gränssättning, föräldra- relation), som vi kan finna i materialet?UrvalUrvalet grundar sig på enkätsvar från 7 602 elever i årskurs 9 och gymnasiets år 2 i Göteborgsstad.MetodUndersökningen som ligger till grund för studien är gjord av Göteborgs stad och baseras på en omfattande enkät innehållande 76 frågor kring alkohol, narkotika, tobak och spel, där vi förvår studie har plockat ut svaren som berör narkotika och cannabis. Studien är av kvantitativ art och har bearbetats i statistikprogrammet SPSS. Resultatet har analyserats med hjälp av det utvecklingsekologiska perspektivet, teorin om sociala band samt utifrån ett risk- och skyddsperspektiv.ResultatVår studie visar att det finns samband mellan ett cannabisbruk och de risk- och skyddsfaktorersom rör skolan och familjen.

Forest as an investment alternative has become more and more popular over the last few years. Between the years 2004 and 2007 increased the price level on forest land with 70 percent in Jämtland. In this thesis a comparison has been conducted between forest in Jämtland and an investment in the stock market. The risk in the two investment alternatives has been included in the comparison. The thesis includes two different studies between the two alternatives.

The field rehabilitation in veterinary medicine has expanded over the past ten years. Animalswith disorders in the musculoskeletal system are often treated. The methods used lacksufficient scientific documentation; however claim to affect the animal's function in a positiveway. In order to investigate the efficacy of different rehabilitation modalities, it is important touse validated evaluation tolls. Therefore, a literature study on pain, pain-scales and functionaltest was performed together a pilot study on a functional test.The aim of the present pilot-study was to investigate a functional test, "Bioarth functionalevaluation scale", used in veterinary medicine.

Purpose: The study examines the risk a rising from the acquisition of shares, and its relation to the expected return. We would like to see how a high-risk portfolio is related to a low-risk portfolio. Although studying the portfolios annual performance.Theory: The theories that have been used in the study are, Capital asset pricing model, CAPM and portfolio theory.Method: The study is based on a quantitative method, the time interval is from 2008 to 2010.The annual reports, historical stock prices for companies and the index are used to perform calculations based on the essay theories.Conclusion: The beta value has positive liner correlation with the expected return. When there are bad times in the world, the companies are negatively affected regardless of industry. The Portfolios developed in the same direction during the time period..

I dagens globaliserade samhälle är det enkelt att placera sitt kapital på olika marknader. Dock kan det innebära både risker och möjligheter för investeraren. Vilket betyder att det satsade kapitalet antingen kan bli en lönsam investering eller gå förlorat. Bör hänsyn tas till landsrisker på aktiemarknaden för att kunna bedöma investeringens lönsamhet?Syftet med studien är att ta reda på vilken betydelse landsrisker har för avkastningen i industri- respektive tillväxtländer.

The real estate industry is a sector where the companies generally have a capital structure which is high leveraged. The financing? with the related terms ? is therefore specifically of high importance for the companies in the sector. Traditionally, the way of obtain financing is by borrowing from the bank. Lately, due to new bank regulations, the banks have become more restrictive in their lending which have lead to a growth of other financing alternatives.

Andelen ungdomar som inte uppfattar några större risker med cannabisbruk har ökat de senaste åren. Ungdomarnas uppfattning av riskerna med cannabisbruk påverkar huruvida de kommer att välja att avstå från eller bruka drogen. Syftet med denna uppsats har varit att se vilka risk- och skyddsfaktorer som påverkar ungdomars riskperception avseende cannabisbruk. Frågeställningarna har varit hur föräldrarna, skolan och vännerna påverkar riskperceptionen. Uppsatsen utgår från en subjektiv syn på riskperception som innebär att inte en faktor ensamt kan förklara om ungdomarna har en låg eller hög riskperception.

This master thesis encompasses an inventory of the older industrial community of Gimo. Investigations of the contamination situation for each industrial area were done. A risk classification according to the Swedish Environmental Protection Agency?s ?Method of Surveying Contaminated Sites?, phase one, followed. The risk classification was done on areas of Iron Work, a rockwool industry and a landfill. Gimo have had iron manufacturing from 1615 until 1945. Gimo have had two blast-furnaces and two smithies periodically.

This Thesis aims to explore how to integrate an IT-system for facilitating anorganizations work with Continous Impprovements.This is done here by examining and analyzing the process within a handful ofcompanies who seem to have been successful with their own implementations. Thestudy is focused on the implementation of one particular system, "System C2".Simliarities and differences between the companies, and the established rule of thumbfor these kind of activities are focused upon. This to emphasis how another actormight emulate some of the apparent success.Part of the core question is found in the title, since Continous Improvement is oftenseen as a relativly low-risk activity, is it then also possible to take a low-risk slow pathto the implementation of such a system in the entire organization?.

Introduction Postoperative wound infections leads to increased patient suffering and cost society money because it leads to longer hospital stays. Previous research shows that patient related risk factors such as smoking, diabetes, Chronic Obstructive Pulmonary Disease (COPD), advanced age (>65 years) a low preoperative hemoglobin level (<140g/L) and a high BMI (> 30) increases the risk of suffering a postoperative wound infection. Aim To investigate whether patients that underwent surgery with Coronary artery Bypass Graft (CABG) in a university hospital in central Sweden in 2013 and had any of these risk factors more often suffer from post-operative wound infection.MethodThe study has a descriptive design and is based on an ongoing infection registration area of operations. The study included 148 patients out of 255 (58%) undergoing CABG in 2013. Possible risk factors were collected through medical record review.Results There was no significant correlation between surgical wound infection and patient-related risk factors such as smoking (not quit smoking four weeks before surgery), diabetes, COPD, advanced age (>65 years), low preoperative hemoglobin (<140g/L) or a high BMI (>30) and suffered a postoperative wound infection.Conclusion More research and a larger sample is needed in the field to produce a reliable result could be presented..

The purpose of this master thesis was to study the water system for mechanically cleaned water at Skärblacka mill, in order to find and evaluate possibilities of using energy more efficiently. The thesis also includes an evaluation of the software tool ?Pumpanalys?Skärblacka mill produces pulp and paper. The large amount of water required is cleaned mechanically through filters and called mechanically cleaned water (MR0). The MR0 water is pumped out to the factory by four crude water pumps.

Evaluations of open Ditch status and function, with an assessment of suitability of a conversion to a two stage ditch as a low maintenance alternative. To illustrate Swedish drainage problems this work focused on two agricultural drainage associations assessed in detail with a new method called MADRAS (Minnesota Agricultural Ditch Reach Assessment for Stability). With the assessment of the MADRAS method estimates were made to conclude the ditches operating problems. This was made through measurements of sediment depths, mass bank failures etc. in order to quantify ditch problems and propose practical actions for improved ditch stability and water quality. The MADRAS surveys were conducted in two main ditches that drains 2900 hectares of land on the northern shores of Mälaren. In the study measurements of the ditch cross-sections were also conducted to compare actual profiles with the original map profiles. The evaluation showed that parts of the studied ditch sections were operatively poor; main reason was mass bank failure, undercut channel banks, sediment aggregations and narrowed ditches. The profile survey shows that a majority of the profiles 80 % has sediment accumulations there remains only 64 % of the original profile from the map.

The main purpose of this master?s thesis is to examine how high school students evaluate the quality of the information available on the online encyclopedia Wikipedia. By doing quantitative research based on questionnaires we expected to find that the means for judging that students use in this situation are most frequently based on a text?s intrinsic qualities in the point of view of its content. It was also our presupposition that 18 and 19 year old high school graduates have received some education in information research and authoritative sources on the Internet.

AbstractBusiness, or business decisions always involves an endangerment from the company?s aspect, but when it comes to business with foreign countries the risk profile looks quite different from the profile the company has when its doing business inside the country. Therefore, it is extremely important for an export company or import company to carefully consider the risks that are enclosed with the deal, before he makes the decision to enter a deal. One of the most important risks a company have to considerate when doing business with foreign countries is the currency risk. A company is exposed to currency risk when either long-term or short-term changes in the exchange rate may affect the result of the company, competitive position and growth.
