The use of insecure networks -such as the Internet- to send and receive information has made the need for preventing unauthorised people reading it yet more important. One of the easiest way to do this is through public key cryptography. However, the problem with this solution is how to tie a specific public key to a certain subject. This is solved by letting a trusted third party issue a certificate that holds, as a minimum, the name of the subject and the subject's public key along with the issuer's digital signature on the information. The rules we make for issuing, revoking and verifying of certificates and the entities that are being used to do so are called PKI - Public Key Infrastructure.

Corporate governance intensified due to the corporate scandals in the USA which led to a new law the so called Sarbanes-Oxley Act (SOX).In 2005 the "Svensk kod för bolagsstyrning" (The Code) was introduced. The main purpose of The Code is to strengthen the confidence in Swedish companies quoted on the Stockholm Stock Exchange. The Code focuses on the working process of boards. The rules set by The Code places higher demands on the board.  Among many other duties the board has to establish long term operational goals and strategy.

The aim of this study is two folded. We wish to investigate if there is a value premium from hedging jet fuel exposure for American and European airlines. We also seek to answer if airlines can affect their probability to default by using Risk Management. During the period 2003 ? 2006 there existed a value premium for airlines that hedged their expected future consumption of jet fuel.

The aim with this study was to describe how the board members of athletic clubs view and value their youth program. A qualitative approach was used in form of interviews. The interviews were made face to face as well as being taped, this to facilitate the analysis. When the board members viewed their youth program to be in alignment with the overall club philosophy there was a discrepancy between their views and the ?de facto? conditions of the youth program.

The work as a personal assistant is sometimes associated with certain problems. Studies have shown that personal assistants often experience indistinct rules and roles concerning what should or should not be included in their duties. This study was undertaken to evaluate problems associated with the profession as a personal assistant, how widespread they are and how they are dealt with. Specifically, the study evaluates if the personal assistants have to do duties that they consider they are not assigned to do. Different roles (formal as informal) are also discussed which may be of current interest in this study, but also how we see people on basis of ethics and moral.

Warehouses are a key aspect of modern supply chains and play a vital role in the success or failure of businesses today. Figures from the USA indicate that the capital- and operating costs of warehouses represent about 22 % of a company?s logistics costs while figures from Europe indicate 25 % (Baker & Canessa, 2009). Because warehousing is such an important function within a company, the authors chose to focus on this in their thesis. The purpose of this thesis has been to examine the significance of a Warehouse Management System (WMS) and item identification with attention to logistic efficiency.

Eskilstuna Folkhögskola is located in Munktellstaden in Eskilstuna. The school has two separate buildings with entrances that are difficult to find. By having two separate buildings, and to be in an area where there are rules and guidelines for the area's environment, makes it difficult to guide visitors to the school premises.The purpose of my research was to examine how to guide visitors to the school, and how to increase understanding that the school's various buildings are connected.Through practices such as site analysis, interviews, I found that the guidelines are not adapted to the current situation that is established in the district.Through theory and empirical material I have produced a design proposal to facilitate Wayfinding to Eskilstuna Folkhögskola. This is presented as a landmark and a clarification of the schools entrances and signage..

In this final thesis a study about welfare indicators in the Swedish milk production has been carried out. The system Swedish Animal Welfare Monitoring Scheme developed by the Swedish Dairy Association has been used as a base and the EU project WELFARE QUALITY® has also been used as a source of information. Focus groups have been used as a qualitative investigating method. This included four focus groups, two with farm auditors from the two different dairies and two with dairy farmers. This method was chosen because in this way one can study how a conversation about a given subject takes form in a respectable way.

The purpose of this Bachelor thesis is to gain insight into themeaning of the mobile library for its users by investigatingwho the users are, how they use the mobile library, why theyuse the mobile library and what the users want from the bookbus service. The methods used are observations, surveystudy and qualitative interviews.The theoretical framework of the study is based onAndersson?s and Skot-Hansen?s model of the public librarywith its four different library profiles, together with PierreBourdieu´s lifestyle theory where habitus and the concept ofcultural capital are used to analyze the role of the book busin people?s lives.My conclusion is that the mobile library is very important toits users since reading is an important part of their lives andit gives them easy access to books of several genres. Themobile library also functions as a meeting place in the localcommunity and creates a link between urban and rural areas..

Det huvudsakliga syftet med projektet är att belysa utställningen och de strukturer som densamma innefattar. Specifikt för detta projekt är att jag har valt att titta på utställningarna på kulturcentret Astrid Lindgrens Näs. Metoden för projektet innebär att blanda empiri med teori vilket resulterat i att jag dels besökt Astrid Lindgrens Näs samt arbetat med teori som beskriver förhållandet mellan besökare och museum, författare och författarskap. Radioverkets syfte är ett ge en viss insikt i hur arbetet på museet genomförs, på ett praktiskt plan. Projektet visar att konventionerna i museet är närvarande och vad som bibehåller dem är rädslan för att besökarna skall missförstå.

Incubators have grown more popular in recent years. Studies have shown that companies that have been part of an incubator grow faster and have a higher survival rate. The Swedish government realizes that this benefits the economy. Therefore they have started different funding programs in order to support the incubators. The thesis aims to explore the underlying reasons for why companies that have been part of an incubator often experience high growth.

Purpose/aim: The purpose of this thesis is to examine if, and in that case how, the municipality of Umeå worked strategically with its communication during 2014 when Umeå was chosen as ?European Capital of Culture?. The research is mainly focused on the outlines of their communication plan, main goals, what  communication strategies the municipality has chosen to and their choice of media channels.Material/method: Two methods are used for this research; qualitative interviews with four employees within the communication team during Umeå2014 and a text analysis of three formal documents which provide the framework of communication policies and media strategies during Umeå2014.Results: The results clearly indicate a well structured, strategic planning outlined in the formal documents. The four people intreviewed all had a good knowledge of the policies and strategies in the documents, they also described their work in accordance with these..

The overriding purpose of this graduate thesis is to evaluate if municipalities and county councils can deviate from the legislation of public procurement during procurement of customer choice agreements within the health and social care area. The intention of this Quasi-market is to provide the users with competition in terms of quality rather then the general principal rule of economic value.My conclusion results in a legal situation without rules of general procedure. So far the authorities make their own regulation in the field of customer choice agreements. The problem lies within the authorization of new contractors and their right to make an appeal against resolutions made by the authorities social care divisions.One solution is to legislate within the present law of public procurement. Another way to solve the problem is to create a lex specialis apart from the present public procurement regulation..

Capital Asset Pricing Model (CAPM) är den prissättningsmodell som mest frekvent används av aktörer på den finansiella marknaden samt i litteratur för att förklara sambandet mellan risk och förväntad avkastning. Teorin grundades under 1960-talet av William Sharpe och tidiga empiriska tester av modellen visade att den med hög förklaringsgrad kunde estimera en framtida förväntad avkastning givet en viss risknivå. På senare år har dock CAPM fått stark kritik eftersom nya empiriska undersökningar demonstrerat att modellen inte längre verkar visa en rättvisande avkastning i förhållande till risk.För att undersöka om den över 40 år gamla modellen fortfarande visar någorlunda rättvisande beskrivningar av verkligheten har vi ställt oss frågan: Går det att med hjälp av historiska data förutspå en riskfylld tillgångs avkastning på den svenska aktiemarknaden?Vid besvarade av denna fråga har studien syftet Att med hjälp av portföljer studera huruvida sambandet mellan risk och avkastning, vilket postuleras av CAPM, stämmer på den nutida svenska aktiemarknaden.Vi har utifrån vår kunskapssyn kritisk rationalism använt oss av en kvantitativ metod för att försöka ge svar på problemställningen, vilken angreps med ett deduktivt tillvägagångssätt. Den teoretiska referensramen behandlar teorier som portföljval, den effektiva marknadshypotesen och CAPM.

Lifelong learning (LLL), a concept dating back to the 1920s, is much used both by the OECD, UNESCO and the EU. But while intergovernmental think-tanks and supranational organisations often use the term in a positive sense, many (not least scholars) are critical of the term. The critique either deals with the lack of a universal definition, that the implicit responsibility for LLL has shifted onto the individual, or that the meaning of the term has shifted from a humanistic one linked to the personal development and a better society to a neoliberal one that involves growth, competition, globalisation and human capital theory. This study is based on interviews with nine trade union representatives on their understandings of lifelong learning. The results showed that while LLL was positively viewed by most, there was virtually no communication vis-à-vis members on the topic, most trade unions have no policy regarding LLL, and responses from representatives were sometimes self-conflicting..
