Finansiella rapporters påverkan på aktiekursen : - Ett bidrag till debatten om slopandet av kvartalsrapporter på Stockholmsbörsen.
This study is based on an ongoing debate regarding the Stockholm Stock Exchange, which centers around the possible abolition of quarterly reports. The purpose of this paper is to contribute to this debate by examining how the relationship between financial reports and stock price correlates. The study's methodological approach is based on the Capital Market Research frame-work in which an ERC model and an extended model are used to measure the relationship. Three hypotheses were formed to categorize the direction of the study, these categorizations treats the differences in impact between quarterly and annual reports on stock price, as well as differences in impact as a casual effect of company size and seasonal sensitivity. The results of the study show that quarterly reports have a stronger impact on the share price than annual reports.
Arbetsvillkorens samband med sjukfrånvaro och sjuknärvaro : En studie av hemtjänstpersonal
Sickness absence is a measure of health and is therefore an important issue. To get a complete picture it´s important to also include in the discussion sickness presenteeism, working while ill, and voluntary absence, staying at home without illness. Working conditions have been proven to play a role for the three aspects which is why this study aims to further investigate the connections between them. The method used was secondary processing on interview data collected from two home care teams, one having a low and the other a high sickness absence. The results showed that there were big differences concerning working conditions, where the group with the high sickness absence perceived more stress, less control and less support from colleagues and superiors.

Historically, much of the produced paper has been transported by vessels, as vessels allow large volumes of goods and deliveries to markets which are difficult to reach with other modes of transportation.
Evaluation of specificity of a walnut antiserum and detection of English walnut (Juglans regia) in food with ELISA and Real-Time PCR
Nuts of all kinds are common ingredients in food. For nut allergy sufferers the frequent use of nuts cause problems and "hidden" nuts in food products may elicit allergic reaction when such foods are consumed. Methods for detecting and quantifying walnut (and other nuts) with high sensitivity and specificity are therefore very important.The objective of this project was to verify the specificity of a rabbit antiserum against walnut with immunodiffusion and to determine the size of the dominant walnut antigens with Western blotting. In addition, a commercial sandwich ELISA for walnut quantification was validated and compared with a qualitative real-time PCR.The rabbit antiserum proved to be less specific but after absorption with cross-reacting nuts and seeds it showed high specificity. The ELISA kit reacted, except for walnut, with pecan and slightly with other nuts and seeds tested.
Design of a Direct-conversion Radio Receiver Front-end in CMOS Technology
In this Master's thesis, a direct-conversion receiver front-end has been designed in a 0.18um CMOS technology. Direct-conversion receivers (DCR) have obvious advantages over the heterodyne counterpart. Since the intermediate frequency (IF) is zero, the problem of image is circumvented. As a result, no front-end image reject filter is required and the channel selection requires only a low-pass filter, which makes it easy to integrate directly on chip. However, the DCR also suffers from several drawbacks such as extreme sensitivity to DC offsets, 1/f noise, local oscillator (LO) leakage/radiation, front-end nonlinearity and I/Q mismatch.
Övervakningssystem för inomhusmiljöer
Övervakningssystem har haft en viktig roll i samhället under en lång period. Syftet med dessa
systemen har inte ändrats, det är alltid säkerhetsaspekten som har varit huvudpunkten.
Effektiviteten på ett övervakningssystem beror oftast på den mänskliga faktorn, någon måste
bearbeta bildflödet som spelas in för att dra definitiva slutsatser. Under senare år har dessa
övervakningssystem, i takt med teknologins utveckling, blivit mer intelligenta. Metoder som
tillämpar automatisk analysering av en given bild har introducerats, vissa av dessa tekniker
har redan hunnit bli en standard. Denna studie ska utveckla en prototyp som använder sig av
tekniken och stresstesta för att identifiera eventuella brister.
Temperature monitoring during transport of test samples
Quality is the main focus in management of all laboratories. Accurate results of the analyses are not only determined by the analytical procedure but also by preanalytical factors. In the total analytical process of clinical specimens, there are many possible preanalytical sources of error. Monetoring of temperature on test samples of the transport boxes is one way to reduce the mistakes in the preanalytical phase.In this study, four laboratories from primary health care were invited to participate. The temperature has been measured on test samples of the transport boxes being delivered to the laboratory.In three cases the temperature remained within the limits, but in the fourth case the temperature varied more than the allowed interval.

Jämförelse mellan antireflexbehandlade- och obehandlade glasögonglas
Introduktion: Det finns många olika ytbehandlingar för glasögon tillgängliga i butikerna. En av dessa är antireflexbehandlingen som har till avsikt att eliminera reflexer som annars uppstår i obehandlade glas.Syfte: Detta är en studie vars syfte var att undersöka om antireflexbehandlade glasögon kan ge upphov till bättre syn jämfört med vanliga obehandlade glas.Metod: Nitton försökspersoner blev tillpassade två par glasögon var. Glasögonen var identiska förutom att det ena paret var försett med antireflexbehandling på glasens främre och bakre yta. Synskärpan testades med en LogMAR-tavla. Kontrastskänsligheten provades dels med Vistech chart på 3 meters avstånd och dels med Mars Contrast Sensitivity Test på 50 centimeters avstånd.Resultat: Testresultaten visade på en statistisk signifikant bättre synskärpa med de antireflexbehandlade glasögonen i normal rumsbelysning.
En familjs upplevelser av ljud - en pilotstudie
Sound surrounds us in a great extent, we all have experiences of sound and this phenomena has a great meaning in our lives. High levels of sound might be harmful for your hearing and might also cause related difficulties such as tinnitus and sensitivity to sound. Studies reveal a connection between the attitudes toward high levels of sound and the risk behaviours in these situations. The purpose of this study was to explore the experiences and meaning of sound and whether the attitudes toward sound will reflect in a family consisting parents and adolescents. A family consisting two parents and two adolescents participated each and one of them in an interview in this qualitative study that has been carried out of a phenomenological approach.
Informativa strukturer och egenskaper som stöd för automatiska processer i människans informationshantering
The purpose of this thesis is to create opportunities for an efficient interchange of information between humans and technology, especially for the skilled user, and put the designprincipal for informative structures and features into practice. Informative structures and features in a large number of information items helps the peripheral visual system to automatically capture knowledge through logical patterns.A field experiment was done to evaluate if informative structures and features, implicate efficient human information-processing, even in a small study. The results was ambiguous because the quantitative part of the investigation didn?t show any significant differences, whereas the qualitative showed that people prefer a dynamic document with a high degree of informative structures and features over a dynamic document with a low degree of informative structures and features. Even if this study was inconsistent, probably because to few subjects where used, the implication of the research that?s behind it is solid.
