Abstract This bachelor thesis discusses existing performance analysis techniques for ARM based architecture processors. This includes a comparison between couple of performance analysis applications installed on two Android test devices. Each application monitored CPU performance of the device in three test scenarios. Each test was done in five iterations. The results were compared for each test and for each application. The results of these iterations were compared to find the most stable application among the rest.

Informationssäkerhet samt IT-säkerhet är ett ständigt aktuellt ämne. I och med att utvecklingenhela tiden går framåt, så uppstår det ständigt nya hål i säkerheten hos ny programvara. Dettaberor delvis på att det självklart är själva programmet som kommer ut först, inte den skadligaprogramvaran. Syftet med den här uppsatsen är att på ett kvantitativt sätt analysera data somsamlas in via enkätsvar, för att få en överblick i hur IT-säkerhetsmedvetna de tillfrågade är närdet gäller mobila enheter. Även vanliga hot mot mobila enheter presenteras, för att få en inblick ivad det finns att skydda sig emot, samt för att öka läsarens medvetenhet angående de olikahoten. Resultatet utav studien visar på att det finns ett behov av att öka medvetenheten gällandeIT-säkerhet för mobila enheter. För att virusskydd för mobila enheter ska få ett störregenomslag, krävs att de stora aktörerna inom IT-säkerhet tar sitt ansvar, och faktisktmarknadsför detta. Enkätsvaren gav en bra bas för att besvara vår frågeställning, och visade påmånga intressanta och relevanta samband.

Adoption of location-based services (LBS) was for a long time below expectations, and most of the studies attribute it to privacy concerns of users. However, many new LBS applications are currently among the most downloaded application for smartphones, particularly entertainment applications. Therefore, this research aims to find out whether privacy concerns still matter to users and to explore the role of the privacy in the adoption of LBS entertaining applications. The adopted methodology is qualitative research and data are collected through interviews and additional information from the smartphones ofparticipants. Ten individuals among university students at Linnaeus University in Sweden are selected for this research, and this sample choice is per their experience with two selected LBS entertaining applications, Pokémon Go and Tinder. As a result, six themes have been recognized to answer the research questions. Low privacy concerns about location information, especially in entertainment applications with negligible effect on adoption have been identified. However, author of this research suggests, that developers of LBS entertaining applications should care for retaining their credibility because it can have an impact on the adoption of their LBS services.

Fördelarna med ett digitalt och gränslöst arbetsliv är många, exempelvis är vi inte bundna till en specifik fysisk arbetsplats. Men det finns också gott om forskning som beskriver hur ett digitalt och gränslöst arbete påverkar oss människor negativt i form av skadlig stress. Däremot finns få förslag på förbättringar på området. Studien syftar till att – ett år senare – göra en uppföljning av ett program för en sund digital arbetsmiljö på ett mindre företag. Det studerade företagets medarbetare genomgick programmet i tre veckor och resultatet var mycket positivt – de kände sig mindre stressade och mer effektiva efter organisationsförändringen. Studiens frågeställningar är: Har organisationsförändringen hållit i sig? Varför? Varför inte? För att undersöka detta fick de som deltog i organisationsförändringen svara på en webbenkät. Utöver det genomfördes en intervju med företagets vd. Studien grundar sig på teorier om organisationsförändringar, stress i ett gränslöst arbetsliv samt hjärnforskning kopplad till förändringsprocesser och digital arbetsmiljö. Ingen tidigare forskning har hittats kring hur insatser för att hantera negativa aspekter av den digitala arbetsmiljön fungerar över tid. Studien visar att programmet för en sund digital arbetsmiljö har varit ett lyckat koncept på det specifika företaget, som delvis har hållit över tid. Medarbetarna jobbar ett år senare i relativt stor utsträckning enligt programmet för en sund digital arbetsmiljö. De delar av programmet som har varit lättast att hålla fast vid är de som handlar om att inte störa kollegorna, som att ha mobilen på ljudlöst i kontorslandskapet. Svårare har det varit att hålla fast vid de delar som handlar om att inte störa sig själv, som att läsa mail och sms på fasta tider. Resultatet pekar på att regler/policies för hur man ska hantera en digital arbetsmiljö samt ett starkt ledarskap är avgörande för att en hållbar sund digital arbetsmiljö. Även individen har ett ansvar.

Cette recherche a pour objectif d'explorer le concept de fidélité oppositionnelle de l'individu ainsi que son potentiel d'enrichissement du concept de fidélité à la marque tel que traditionnellement abordé. La fidélité à la marque, définie jusqu'ici par un comportement d'achat répétitif accompagné d'une attitude positive envers la marque choisie, acquiert ainsi une nouvelle composante issue de la littérature sur l'anti-consommation et la résistance qui constituent, aux côtés de l'identité sociale et de la recherche d'équilibre, le cadre théorique sur lequel est fondé ce travail. S'appuyant sur le terrain des smartphones, la méthodologie de recherche est articulée autour de trois sources de données principales : des commentaires d'internautes en ligne, des entretiens et des récits de vie. Ces données ont été traitées grâce à une analyse de contenu thématique classique. Les principaux résultats mettent en avant l'existence d'une fidélité oppositionnelle de l'individu qui s'appuie sur une attitude et un comportement positifs à l'égard de la marque choisie et négatifs à l'égard de la marque évitée. Qu'elle se présente sous sa forme attitudinale et/ou comportementale, la fidélité oppositionnelle évolue dans le temps aboutissant ainsi à différents profils de fidèles oppositionnels. Enfin, ce phénomène émerge comme une réaction/résistance au comportement de la marque, une volonté de distanciation par rapport à une image de consommateur-type ou un évitement suite à une expérience négative avec une marque donnée. Ces résultats permettent aux managers de définir des stratégies de défense du capital–marque de leur portefeuille de marques et de résister ainsi aux attaques des concurrents sur des marchés devenus de plus en plus concurrentiels. / This research aims to explore the concept of oppositional loyalty of the individual and its potential to enrich the concept of brand loyalty as traditionally addressed. Brand loyalty, so far defined as a repetitive buying behavior together with a positive attitude toward the chosen brand, acquires a new component borrowed from the literature on anti-consumption and resistance that constitute, together with social identity and balance quest, the theoretical framework on which this research is based. Based on the smartphones field, the research methodology is structured around three main data sources: online internauts' comments, interviews and life stories. These data were processed through a classical thematic analysis of content. The main results highlight the existence of an oppositional loyalty of the individual that is based on positive attitudes and behavior towards the chosen brand and negative ones towards the avoided brand. Whether it is manifested under attitudinal and / or behavioral form, oppositional loyalty evolves over time, resulting in different profiles of oppositionists loyal. Finally, this phenomenon emerges as: a response / resistance to brand behavior, a desire to distance oneself from the image of consumer-type or an avoidance following a negative experience with a particular brand. These results allow managers to define strategies for defending the brand equity of their brand portfolio and thus resist the attacks of competitors on markets that are becoming increasingly competitive.

The main subject of this thesis is the security of Android platform mobile devices. The goal of the thesis is to design and develop an application that will check given devices from the security point of view and to check the security of applications developed as the subject of theses created in the last few years at the University of Economics. In the first part of thesis there is an analysis of ways to secure the Android platform devices and applications and ways to attack them. Both the offline and the client/server architecture applications are also taken into consideration. The next part includes a security analysis of the selected application based on the beforehand determined criteria. An analysis and development of the application designated to examine the security of the given device is next. The outcome of the thesis is an easy to use application that can be launched on the mobile devices running Android 2.2 Froyo and higher.

The aim of this thesis is to describe current trends in global retail, the current state of retail in Czech Republic and possible need of bringing innovation to the outburst of Millennials generation economic activity. Introduction is devoted to theoretical description of retail and its meaning. As part of the thesis, there is a significant part containing relations within the worldwide retail and also its current trends and development. Furthermore, part of the thesis is devoted to the development and ongoing evolution of retail in the Czech Republic. Theoretical definition in the third chapter deals with buying behavior as well as the factors which have an impact on it. Millennials are the bearers of the innovation need in the world retail sector. The thesis put emphasis on this generation essential features characteristic, as well as their purchasing behavior. Quantitative research includes evaluation of their behavior and attitudes on the czech market in relation to information about groceries and consumer goods, then to their use of technology (smartphones) in the buying process of groceries and consumer goods, and also evaluation and description of their specific attitudes to purchase behavior and different characteristic aspects resulting from global characteristics of Millennials.

This study aims to examine the function and vulnerabilities of biometric systemsintegrated in smartphones, as well as techniques for circumventing the securityof these systems. These techniques are then used against a selection of smart-phones in order to gauge the resilience of their biometric security. The function,vulnerabilities, and techniques associated with these systems are compiled usinga literature study of published papers and books on the subject. The performedexperiments apply these techniques in the form of presentation attacks directed atthe fingerprint-, face- and iris recognition systems of the examined smartphones.The result of the experiments showed significant differences between the differentsmartphones, where some exhibited flawless security and others showed significantsecurity flaws. Both fingerprint and face recognition systems were successfullycircumvented, while none of the iris recognition systems were breached. No clearlink could be observed between the cost of the device and success rate of attacks,while only devices using the Android operating system were breached. The resultsundeniably showed that some smartphones are vulnerable to the employed tech-niques. It also showed that some of the tested devices had managed to implementmeasures to counteract the applied presentation attacks. The root cause of thevulnerabilities showcased in the experiment is due to the fact that biometric traitscan be copied and reproduced, highlighting a basic flaw of such systems.
