Utlakning av tungmetaller frÄn Skörby deponi
The purpose of this thesis has been to assess whether leaching from one particular Swedishlandfill site, Skörbytippen, is contributing to elevated levels of heavy metals in a ditch runningfrom the landfill site to the lake MÀlaren in the communal region of HÄbo kommun. Since theditch is stretching approximately five km downstream from the landfill site, in situ observationsand maps with known points of inflow was utilized to determine appropriate test points for thecollection of samples.Soil, water and sediment samples were collected and analyzed for content of organic material, pHand conductivity. Data on plant-available elements and total amounts of heavy metals wasacquired through ICP-analysis.The results show that the Skörby landfill is currently in the methane-forming anaerobedevelopment phase, which indicates that the concentration of free and complex-bound metals inthe leachate water should be low due to chemical binding with other landfill compounds. The pHof the sediment samples was generally one unit higher than the soil samples and some of themeasured data, such as pH and conductivity, show that an environmentally disturbing dischargeof some kind of strongly alkaline chemical(s) has been made from Benders? takpanneindustri inclose proximity to the landfill.
BetongbjÀlklag med limmad matta : olika behandlingars effekt pÄ alkalitet, fukthalt och emissionsbildning
This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).
Personlig integritet och kreditupplysning
Most people would agree that privacy is a civil right, and that we should not be deprived of this civil right for other than legitimate reasons. The difficulty lies instead in how to decide where the legislative boundary should be drawn for the right to privacy, in order to protect the individual from an undue intrusion of his privacy. There are a number of areas where the right to privacy comes in conflict with opposite interests. One of these areas is credit report. In this master thesis the author discusses questions as, what is the meaning of the word privacy, and whether the protection of privacy is sufficient in the legislation concerning credit report? Also a comparative study of the Swedish and the English regulation is performed.
Implementeringen av Basel II-regelverket i Sverige : En jÀmförande studie över svenska storbankers kapitaltÀckning
Problem and purpose: The authors were interested in studying how large Swedish banks managed liquidity risks when facing the financial crisis of 2008 and whether the implementation of Basel II framework had an impact on the major Swedish banks' capital adequacy. Furthermore, the authors intend to examine how, based on the analysis of the implementation of Basel II, the introduction of Basel III will affect major Swedish banks' liquidity in the future.Method: The essay is written from a quantitative approach and has a deductive perspective. Data was collected from the annual reports of the selected banks to later use relevant theories to analyze the work.Theory: This part of the essay presents relevant theories, a detailed description of the Basel regulatory framework and its requirements, rules for capital adequacy and to relevant key to achieve the Basel regulatory requirements are considered. Furthermore the authors present criticism of the Basel framework and a summary of the key theoretical points to be used for analyzing empirical data.Empirical: In this chapter the data collected from selected banks is presented and processed.Conclusion: The essay authors present the deficiencies and weaknesses that make the Basel II regulatory framework inadequate for the Swedish financial market. Essay authors also present their opinions regarding how the latest form of the Basel regulations could have a more significant influence on the long-term stability of Swedish banks and how this may increase protection against potential liquidity risks..
lÀraren och datorn : en studie av IT-kompetens hos lÀrare i gymnasieskolan
Studien undersöker samband mellan gymnasielÀrares bakgrund och IT-kompetenser samt hur arbetet med IT organiseras pÄ gymnasieskolor och vilka möjligheter till kompetensutveckling som gymnasielÀrare har. Samtliga data kommer frÄn en anonym webbaserad enkÀtundersökning som besvarades av 62 gymnasielÀrare pÄ olika gymnasieskolor i mellersta Sverige (utskick till cirka 290). Insamlad data analyserades kvantitativt i SPSS och Microsoft Excel och presenteras som tabeller och diagram. Intressanta fynd i analysen Àr att yngre respondenter skattar sina egna IT-kompetenser högre Àn Àldre respondenter och att det finns en tydlig skillnad i att kvinnliga respondenter ser betydligt större behov av kompetensutveckling Àn manliga respondenter. Vidare ses mjukvara för ordbehandling och skolans lokala lÀrplattform som tvÄ av de viktigaste verktygen i yrket, medan förmÄgan att skapa egen media i genomsnitt ses som mindre relevant.
Hyresbostadsfonder - ett placeringsalternativ för vÀlbÀrgade?
Hyresbostadsfonder Àr en ny placeringsform i Sverige som erbjuder privatpersoner, företag och institutioner att Àga hyresfastigheter och erhÄlla avkastning frÄn förvaltningsöverskott och vÀrdeökning. I denna studie jÀmförs aktie- och obligationsfonder med en simulerad hyresbostadsfond ur ett risk kontra avkastningsperspektiv. Fonden baseras pÄ data över den svenska fastighetsmarknaden frÄn Svenskt Fastighetsindex och Investment Property Database, dÀrför att placeringsformen Àr ny och det rÄder brist pÄ historisk data frÄn verkliga aktörer.MÄlet med studien Àr att besvara om hyresbostadsfonder Àr ett konkurrenskraftigt alternativ till aktie- och obligationsfonder. Utöver finansiella jÀmförelser redogör författarna eventuella dolda risker och nackdelar med placeringsformen.Resultatet frÄn studien visar att hyresbostadsfonden har presterat bÀttre Àn bÄde aktie- och obligationsfonderna under perioden 1988-2008. Bidragande faktorer till denna utveckling har identifierats och redovisats.
Patent och företags storlek - finns det en tröskel till intrÀde?
Several studies have investigated the relationship between different measures of innovative activity, such as patent statistics and R&D expenditures and some have looked deeper into the differences between large and small firms regarding number of patents issued per employee or per R&D dollar. In this paper, the objective is to find out if there are any indications of a barrier to entry (due to economical factors, lack of knowledge etc) for small firms to get into the field of patent handling. The approach is to first set up a hypothesis based on some simple assumptions about how firms would make decisions about whether to apply for a patent or not and thereafter use econometric methods in an empirical investigation. The data used for this study are figures on number of employees, number of patents granted and R&D expenditures for the Swedish firms in the pulp and paper industry. The main conclusion is that, based on the analysis of the data from this rather limited group of firms, no such barrier can be seen..
Företagsstyrning i kooperativa organisationer - Vilka likheter respektive skillnader finns det mellan en konsument- och en producentkooperation?
A co-operation is established when a group of people, sharing the same preferences and values, come together in order to satisfy a common need. The co-operative association should be democratic, governed and supervised by its members and open to everyone.
The purpose of this article is to, from our ideal type, study similarities and differences regarding the corporate governance of the consumers? and the producers? co-operative movement. The motive behind our choice of alignment is that the mechanisms of corporate governance often are described from the perspective of the joint-stock company, making it valuable and interesting to study these mechanisms from the co-operative point of view.

För nÀrvarande investeras det mycket i olika BI-lösningar och företagen behöver veta vad resurserna bör lÀggas pÄ. I dagslÀget finns det ingen modell som bedömer ett företags arbete med Business Intelligence utifrÄn ett flertal dimensioner.Syftet med den hÀr studien var att utveckla en mognadsmodell för Business Intelligence och sedan jÀmföra de undersökta företagen Axfood, Scania och Systembolagets mognad.
Internkommunikation och organisationsidentitet. En kvantitativ undersökning av internkommunikation och organisationsidentitet inom PrimÀrvÄrden
Background and Problem discussion: Strategic evaluations are important as they providecrucial information regarding Swedish development assistance and recommendations on howto face problems and inadequacies found in the evaluations. Therefore, the follow up ofrecommendations is of great significance as well. Unfortunately, SIDA?s ManagementResponse system for follow-up of strategic evaluations has not been functioning in asatisfying way and needed actions have not been taken. Thus, Swedish developmentassistance has been criticised for the lack of implemented actions and the public has startedto question the work carried through by the organisations.
Implementation av webbsida för rekommendationssystem med anvÀndaruppbyggd databas
The goal of this project was to create a web-based, crowd-sourced, correlational database, that easily allowed users to submit objects and receive correlated objects as results. The webservice was created in the web development languages of HTML, CSS, PHP and Javscript, with MySQL to handle the database. Simultaneous development was kept in check with the aid of the source code management system GIT. Upon completion, the service contained several HTML-views, the ability to add and rate objects, a per-object dedicated page with information parsed from Wikipedia.org, and a view with objects ranked in accordance to the preferences specific to the current user. Roughly a month after the beginning of development, the website was publicly launched and promoted in order to collect data, and improvements were added to the website as needed.
Förekomst av kontaminanter i importerad fisk : en litteraturstudie
A literature review of contaminants; cadmium, methylmercury, dioxins, and PCB, for eleven different fish species (Greenland halibut, gilt headed bream, sea bass, wolffish, hoki, ocean perch, angler, Nile perch, pangasius, red snapper and tilapia) that were selected in concurrence with the National Food Administration. The result can be used by the National Food Administration to gain further knowledge about the different fish species to be able to continue to give advice to varied risk category and the public. The gilt headed bream and sea bass were the only fishes whose values for mercury exceeded the limit of 0,5 mg/kg (EU Reg. 1881/2006). In the angler, Nile perch and pangasius the mean value of mercury didn?t exceed the limit, however in some individuals the mercury content did exceed what is allowed.
?Man mÄste vara macho, dÀrför att mesen inte gÄr hem? : En kvalitativ studie om kvinnors vÄld mot mÀn i heterosexuella förhÄllanden sett ur myndigheter och ideella organisationers perspektiv.
The intention of this qualitative study is to describe and analyse women's violence against men from the perspective of authorities and volunteer organisations. Data has been collected trough semi-structured interviews with six respondents stemming from the police, social services and a help organisation for men respectively. The data has been analysed using existing research and common theories about power, sex and gender. The study shows that IPV does not only contain physical violence, but also acts of psychological-, sexual-, economical-, material-, and latent violence as well as the fact that one act of violence almost never exists alone. It is shown that women more often use psychological abuse against their partner then men do and also that men tend to stay longer in an abusive relationship then women.
