Neonate mortality in fallow deer (Dama dama) in relation to bed-site selection and habitat use
The level of neonate mortality in a free ranging fallow deer (Dama dama) population at the Koberg estate in south western Sweden was investigated using radio-tracking techniques. During this study a total of 36 fawns (17 ?, 19 ?) were captured and marked with vhf or gps radio collars; 12 fawns in 2008 and 24 fawns in 2009. The neonate mortality calculated by the Kaplan-Meier method was 23.6 % and the mortality caused by predation was low, since only 1 of 8 non-surviving fawns died from predation by red fox (Vulpes vulpes). The spatial behavior of the fallow deer neonates were examined at two different levels i.e.
Finansmarknadens reaktioner på naturkatastrofer förorsakade av enskilda bolag : En eventstudie av katastrofen i den Mexikanska golfen 2010
Bakgrund: Den 20:e april 2010 inträffade en explosion på BP:s oljeplattform Deepwater Horizon i Mexikanska Golfen. Explosionen uppstod på grund av metangas som under högt tryck expanderade på plattformen och sedan antändes. Detta ledde senare till att oljeplattformen sjönk och ett stort okontrollerat oljeläckage uppstod på cirka 1500 meters djup. Att explosionen i den mexikanska golfen har påverkat BP negativt och varit mycket kostsamt för företaget är uppenbart, börskursen hade som mest sjunkit med cirka 60 procent. Det kan vara intressant att undersöka huruvida denna katastrof, utlöst av en enskild aktör, också har spridit sig över till andra aktörer i Olja & Gas sektorn.Syfte: Syftet med denna C-uppsats är att undersöka huruvida BP:s katastrof i den Mexikanska golfen har påverkat andra aktörer i samma sektor (Olja & Gas sektorn).Metod: Sekundärdata presenteras som en kvantitativ ansats i form av siffror och för att kunna dra slutsatserna använder vi oss av en deduktiv ansats.I denna studie tillämpas en metodikteknik i form av en eventstudie, där beräkningar av den abnorma och förväntade avkastningen baseras på marknadsmodellen. Vidare har två hypoteser testats, där syftet med Hypotes I är att pröva huruvida information om händelsen i den Mexikanska Golfen påverkar andra företag i samma sektor som BP.
Har intressenterna förtroende för revisorerna?
The purpose of our essay is to investigate the trust in accountants. The method we used to investigate the trust was a survey and a questionnaire was used to collect the data. The data was gathered from three different groups, shareholders, lenders and tax authority. When we analysed the data we found out that the groups trust in accountants were neither strong nor weak. The results can be generalized on all the three groups because the observations were scattered around the means and we used random selection to collect the data.
Utvärdering av Near Field Communication och Certified Wireless USB : Säkerhet vid utveckling av applikationer
Today?s society is one where technological advances are made daily, which increases the need to stop and assess the risks against users? integrity when integrating new technology in contemporary systems all the greater. We have taken two technologies, Near Field Communication and Certified Wireless USB, whose envisioned area of use is to be integrated into mobile phones, and evaluated what security threats are revealed for the respective technologies. The threats against security have been identified through research of the standards and existing reports for each technology. Practical experiments have not been conducted on account of us not having access to any equipment to run such trials.

Weaknesses in different NFC protocols will be presented and suggestions on how to counter certain weaknesses will be discussed. This survey will be valuable for companies interested in protecting their data when using or planning to use NFC systems..
Kyrkan som immateriellt kulturarv En studie i kulturvårdens förhållningssätt till liturgiska värden
This master thesis aims to examine the methods of the conservation field and their visionabout maintenance and change, in terms of liturgical values. This is to be able todetermine if there is a need to develop the methods that the field of conservation has tosafeguard the intangible cultural heritage of the churches.This is mainly a literature review, focusing on different tutorials from the Swedish nationalheritage board, and different texts on liturgy aswell as Unesco's Convention for theSafeguarding of intagible Heritage (2003), ratified in Sweden in January 2011. A casestudy of the practical work has been carried out on three churches that have undergonechange. The application process and the results were important for this study.The conclusion is that the conservation field have ambitions to preserve the liturgicalvalues, but they do not have sufficiently developed methods to do so. Nevertheless, itappears that most cases of change in churches, increases the liturgical values..
Diet och identitet : Analyser av kol- kväve- och svavelisotoper på indivier från det kristna senvikingatida gravfältet i Björned, Torsåkers socken, Ångermanland
This paper deals with the late Viking age/early medieval grave field in Björned, Torsåker parish, Ångermanland County in northern Sweden. The grave field in Björned is rare because it has all the signs of being Christianized before the surroundings. This awakes questions such as if the people of Björned came from another place and brought the religion with them or if someone else did that for them. To find these answers I have analysed the stable isotope ratios [delta]13C, [delta]15N and [delta]34S in human bone collagen. Through these stable isotopes we can not only see what the people consumed but also where their food had its origin.
Kandidatarbete
An analysis in the work of Martin Kellermans comic ?Rocky? of the interaction between the male and female characters and of how each of their gender are portrayed. We are going to find out if it is probable for young adults to be affected by any eventual gender-stereotypes that we can find in ?Rocky? or if ?Rocky? consolidates a stereotypical image of men and women that young adults might have developed through different media. We conduct this analys by first reading through random seleceted ?Rocky? books and present some of the comic strips where men and women interact with each other or discuss the opposite sex..
Anst?lldas attityder till chefers ledarskapsstilar inom fackliga organisationer - En kvantitativ studie om genusrelaterade attityder till ledarskap
This study was based on a quantitative method to examine gender-related attitudes towards leadership styles among employees in trade union organizations in Sweden. The aim of the research was to investigate and understand how gender relates to attitudes regarding leadership within these organizations. The study was based on research questions related to preferences for different leadership styles and the impact of gender on these attitudes. The study incorporated previous research and relevant theoretical frameworks such as leadership theories, gender theories, and theories on prejudice against female leaders to contextualize our findings. Data were collected through a survey using a convenience sampling method, targeting employees of trade union organizations in Sweden.
Potatisens specifika vikt och kokegenskaper med hänsyn till odlingsplats och sort :
The boiling properties are an important quality issue of the potato. In order to obtain adequate boiling properties the growth of the potato needs to be controlled and interrupted at the right time. However, it is difficult to determine when to stop the growth. Specific gravity can easily be measured and can sometimes be used as a tool for estimating the boiling properties.
This report discusses different aspects of the specific gravity of the potato and how it can be used as a tool to determine the appropriate time for vine killing.

Förtolkning inför skogsbruksplanläggning med laserdata (NNH), eller traditionell flygbildstolkning?
The purpose of this study was to investigate produced laser data from the new national height model's airborne laser scanning in Sweden, what quality it has and whether it can be used for forest management planning. From airborne laser scanning one can obtain information on forest variables such as tree species, height, diameter and basal area. Norra skogsägarna is the principal employer of this project and they wanted know to the quality of the laser data which needs to cope with their standards. If the laser data the quality required it can replace some of the operations performed by field planners.
To examine the quality of the produced laser data a control tax assessment has been performed in 30 forest departments. This was done in an objective manner.

Så nås samstämmighet mellan logistik och företagsstrategi : en analys av hur den logistiska strategin ska utformas för att stödja företagets överordnade strategi
Background: Due to an increasing globalization the competition has increased and this has lead to overcapacity and falling prices on markets today. The subject field logistics has during the last decades been given increasingly significance and has become a way to handle the competition. Theories clearly point outthe importance that a concordance exists between logistics and superior strategy but few, if any, authors give further details about how this adjustment should be made. Purpose: The aim of this thesis is with a case study approach survey if the subject field, which describe the importance that logistical solutions correspond with the superior strategy, is known and implemented in a company. We aim to develop the subject field through our empirical findings.
Är Stockholmsbörsen predicerbar?
I den här uppsatsen testas huruvida Stockholmsbörsen är predicerbar, i motsats till den icke-predicerbara teorin ? Random Walk theory. Till skillnad från majoriteten av tidigare studier, undersöker jag predicerbarhet för enskilda aktier, och inte bara som ett aggregerat fenomen i form av ett index. Resultatet av studien visar att Stochholmsbörsen som en homogen grupp inte gå att predicera. Däremot, då varje aktie undersökts i isolerad form, uppvisar majoriteten av aktierna ett predicerbarat beteende ? i form av Mean Reversion, alternativt Mean Aversion..
