In todays high-technological society where the Internet plays a central role in our day-to-day life, many e-retailers are not able to attract customers to complete a transaction on their website. In order to succeed, many e-commerce sites must improve several safety aspects regarding online payment, in order to be perceived as a reliable and secured retailer. The purpose of this paper is to investigate if increment in various combinations and aspects in online payment will in fact improve the customer's perception of the e-retailer and result in completed transactions. In order to investigate this aspect, an experiment was conducted to be able to compare eight independent groups, that each had been exposed to a different security scenario on the online payment website of either a known or unknown retailer. Our results clearly prove that perceived security of the retailer's payment website increases willingness to purchase from the retailer.
Folkpartiets syn på svensk säkerhets- och utrikespolitik 1956-1974 : En jämförande analys av Folkpartiets syn på svensk säkerhets- och utrikespolitiska frågor i förhållande till regeringen
The socialdemokrats? long possession of government power from the 1930?s to 1976 gave them the opportunity to put their stamp on Swedish domestic and foreign affairs in the shadow of the cold war. The government policy in security and foreign affairs, therefore, was that of the socialdemokratic party. The stance of the government has been researched, but it lacks focus on the opposition. The purpose of this paper is to analyse Folkpartiet´s view of security and foreign affairs in comparison with government policy.
Libyenkrisen ? en humanitär intervention? : En kvalitativ textanalys som syftar till att förklara motiven bakom NATO:s och FN:s beslut att intervenera Libyen
Humanitarian intervention is a concept that generates several problems in our time. The idea of humanitarian intervention concerns the modern norms of sovereignty and noninterventional principals. It also concerns the conventional norm, which declares that states are not allowed to interfere in other states? internal affairs. The use of military force to implement humanitarian intervention is restricted according to international law.
Att färdas i symbios : ett gång -och cykelstråk anpassat efter trafikanternas rörelsemönster och behov
The aim of this paper is to examine the layout of public spaces and its effect on human behavior with focus on the relation between pedestrians and cyclists movement patterns in a specific path. The study emanates from the security aspect of pedestrians and cyclists, and builds upon previous theories and empirical studies about perception, security, information design, environmental psychology and behavior. The result shows that individual behavior and movement pattern differs with age, purpose, physical- and other conditions, and layout of the surroundings. A design proposal for improved layout of a path and a node between different oncoming paths has been developed to aid the users? needs, where a separation of walkways and bike lanes forms zones of security for the purpose of better orientation and a better flow between the users..
Skillnader i kungsörnens (Aquila chrysaetos) flyttningsmönster beroende på ålder och klimatfaktorer : En studie för skyddet av kungsörn
This study examines the factors that influence the seasonal movements of Golden Eagles (Aquila chrysaetos), and can thus provide important information that helps to improve the protection of the species. There were two main purposes of this study. First, I wanted to analyze the difference between preferences of juvenile and adult Golden Eagles in their choice of southern or northern hibernation areas. Do younger eagles prefer moving longer distance to southern areas of Sweden? Second, I wanted to investigate how the climate influenced the choice of date of migration in the fall.
Måltiden som lärandesituation i förskolan : en kvalitativ studie om pedagogers syn på barns övergripande och hälsofrämjande lärande i förskolan genom den pedagogiska måltiden
The purpose of my study has been to find out how four preschool teachers at four different preschools looks at the pedagogical meal from a health and overall learning perspective. I also want to examine how, through the pedagogical meal the preschool teacher works to promote children´s learning and give them an understanding of need to safeguard their health. To achieve my aim I set the following questions;What are the different types of learning preschool teachers believe that children can acquire the basis of the pedagogic meal?How do preschool teachers describe their work from the pedagogical meal to benefit children´s overall learning?How do preschool teachers describe their work at the pedagogical meal for the children to gain an understanding of their health?The study is based on a qualitative method with interviews and observations, triangulation. The theoretical approach to this study is based on the socio-cultural perspective to learning and development.
Bluetooth and security
Detta arbete behandlar hur Bluetooth fungerar samt säkerheten kring Bluetooth
och några allmänt tillgängliga attack verktyg.
Syftet med uppsatsen är att försöka fastställa hur säkert Bluetooth är i dagens
läge. Bluetooth har länge varit tillgängligt för att utbyta data över korta
avstånd. Därför har man valt att implementera det i kommunikationsenheter som
mobiltelefoner och laptops med mera. Det har funnits en debatt om hur säkert
Bluetooth är. För att kunna genomföra denna undersökning så har vi satt oss in
i hur Bluetooth fungerar, vilka allmänt tillgängliga attacker och
implementationer av dessa, som finns.
Leder storskaliga landinvesteringar i jordbruk till hållbar utveckling? En fallstudie av projektet ProSavana i Moçambique
Large-scale land investments is not a new phenomenon, but increasing prices on food and agrofuels have inflated prices on land and has led to an enhanced interest in landinvestments from a range of different actors. The ProSavana project in the Nacala corridor in the Nampula province, northern Mozambique is a large-scale land investment with the purpose of establishing intensive commercial agriculture and is planned to be implemented this year (2013). The project is financed by Brazil and Japan in collaboration with the government of Mozambique. It is not quite clear how large-scale land investments affect the areas they are implemented in and how they can affect the possibilities for sustainable development in these areas. Both opportunities and problems can be observed within the social, economic and ecological dimensions of sustainable development.
Säkerhet och integritet i närfältskommunikation
Context. In today?s society we use smart cards in many areas, NFC is a smart
card technology that allows contactless interaction between a reader and the
tag, the tag is often in the form of a card. NFC can be used for various
payment methods or as access card to a building which makes life easier. In
previous studies, the technique has proven to be weak to attacks using an NFC
reader connected to a computer.
Säkerhetshot och lösningar för privatpersoner med bredband
As more and more people gain access to broadband in their properties, the
security threats get bigger. A lot more people also have computers that they
carry home from work where they store important information concerning the
company. The information stored on theese computers can be very easy to
retrieve if you have the will and the skill to do it. Very few people have any
knowledge how to protect themselves from theese threats..
Rysslands politiska utveckling : En fallstudie över svensk säkerhetspolitik
The Swedish security policy has changed from stressing neutrality to embrace co-operation within the EU and other organisations. New threats like terrorism, boarder-crossing criminality and natural disasters require new ways to deal with this type of problems to protect the society. Since the beginning of 21st century the high Russian economic growth has made it possible for the country to play an increasingly role as a superpower on the international political stage. In the same time the democratic development has been replaced by an autocratic rule which has obstructed the Russian- European relations. From a Swedish security policy view the Russian political development is of importance and the picture of Russian as a threat has changed from 1996 to 2008/09.
Hur används vetenskap och forskning i den politiska debatten? : Idéanalys av debatten kring försäkringsmedicinskt beslutsstöd
How is research and science being used in political debate? An idea analysis of the debate about försäkringsmedicinskt beslutsstöd (decision tool in healthcare security)This is a case study on different types of research use (utilization) The aim of this paper is to examine how the politicians make use of expertise and research in the parliamentary debate surrounding the decision tool in healthcare security (försäkringsmedicinskt beslutsstöd).

In this case study the qualitative method of idea analysis is being used on the empirical material. The tool of analysis is based upon the theories of research use by Amara et al.
Ohållbar marknadskommunikation av seriösa hållbarhetsaktörer: en fallstudie av H&M och Max
Problem: Företag ägnar sig åt ett seriöst hållbarhetsarbete, men det finns anledning att tro att detta inte speglas i deras marknadskommunikation. Förändringar i marknadskommunikation tenderar att vara konservativa, då företag väntar på en indikation från marknaden för ökat intresse av hållbara produkter.Syfte: Huvudsyftet med arbetet är att undersöka huruvida företag inom ?fast fashion?- och ?fast food?-industrierna som gör ett gediget hållbarhetsarbete också använder en marknadskommunikation som är ohållbar. Som en del av detta arbete kommer en grundläggande definition av ohållbar marknadskommunikation att konstrueras genom teoristudier.Metod: En kvalitativ undersökning har använts, då en fallstudie med bildanalys har genomförts, med empirisk data hämtad från företagens marknadskommunikation.Teori: Den teoretiska referensramen grundar sig i teorier kring marknadskommunikation, hållbarhetsaspekter och konsumtionssamhällets konstruktion.Resultat: Det empiriska materialet redovisas genom fallstudieberättelse, baserad på bildanalysen av marknadskommunikationsmaterial som utförts och den analysmodell som har konstruerats.Analys: Empiriska data som insamlats har jämförts med de teorier som vi använt oss av i den teoretiska referensramen. Resultaten har analyserats för att hitta övergripande likheter inom företagens marknadskommunikationSlutsats: Företag inom ?fast fashion?- och ?fast food?-industrierna som arbetar seriöst med hållbarhetsarbete kan också använda en ohållbar marknadskommunikation enligt den definition som har konstruerats..
Post-harvest losses in fruit supply chains : a case study of mango and avocado in Ethiopia
Food insecurity is a great problem worldwide and Ethiopia is one of the sub-saharan countries that are suffering from poverty and food insecurity and a large part of the population are living in a state of undernourishment. To reduce these problems, a successful horticulture production can be an important factor. Compared to other crops, fruit production in Ethiopia has not been a large part of the agricultural sector. However, the demand on the domestic market is increasing as well as the production for avocado and mango. To increase Food security it is important to focus on ways to decrease post-harvest losses of food products and not only have the productivity of agriculture in focus.
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.
