Mer värde i mobilen och mindre i plånboken - En fallstudie av mobila betalningslösningars genomslag i Sverige

This thesis presents the question of a possible breakthrough for mobile payment solutions in Sweden. The way payments are made and the way cash is being used in the society is changing. To be accepted as an alternative method, if cash isn't king anymore, the new technology will have to acquire user acceptance. In this thesis a case study of Swish, a mobile payment solution for P2P-payments, is presented. The focus of the study is customer value and technology acceptance of the service.

Boka en bibliotekarie - en studie i förmedlad informationssökning

This master thesis deals with events, dynamics and problems of mediated information seeking within the context of a new information service called "Book a librarian". The study, based on a survey and interviews both in academic and public libraries and participant observations in academic libraries, has its theoretical base in the cognitive theory of information retrieval interaction. The cognitive view is used to throw light upon the need of an ongoing dialogue during the session in order to detect the information needs of the user and to conduct a successful retrieval of information. The communicative interaction is seen as threepart interaction between the intermediary, the user and the information system, where the current cognitive states of all three participants are involved. The study shows that the cognitive obstacles for a successful mediation and information retrieval are mostly connected to participants current knowledge of the subject and of the retrieval techniques.

Grönskande balkongkonstruktioner : Jämförande arkivstudie av balkongkonstruktioner anpassade för urban odling

Urban agriculture is a current topic and this study examines the possibility of cultivating on balconies in the city. The study was performed at Uppsala University and examines, from a structural engineering perspective, how different existing balcony/terrace structures are affected by cultivation. A cultivation balcony defined in the study as a balcony/terrace which is specifically designed for cultivation. Three units of study have been selected according to this criterion. Four factors were examined, these were loads, moisture/water, economy and cultivation.

Mätning av partikelmassa i avgaser från en dieselmotor

This master thesis was a continuation of a previous study in the diesel exhaust characterization, which is part of the academical work embedded in the EMIR-1 project. The main objective of this thesis work was to finish the installation and make the proper modifications of the particulate mass measuring system located in one of the engine test cells at KTH, in order to be able to measure the mass of the particles from the exhaust of diesel engines.This experiment requires a diluted flow sample from the exhaust that should be sent to the device that makes possible the measurement of particle mass, called TEOM. In the first stage of this project, the objective was to study and make the proper modifications in the existing KTH diluter because there were several problems to obtain a constant dilution ratio from it during tests.This modifications were made and it resulted in a great improvement in the maximum inlet and outlet flow that this diluter can handle. Therefore another modification is proposed for controlling the inlet exhaust flow so it will be possible to regulate the dilution ratio and make it constant along a wide range of engine loads and speeds.The second and most important stage was to make particulate mass measurements possible by analyzing the frequency signal from the TEOM device. The idea was to obtain the frequency of oscillation from the tapered element in the TEOM, and therefore with the proper correlations, be able to predict the particulate mass concentration in the exhaust flow from the engine.An electrical problem in the TEOM circuit was detected and corrected, so the signal that carries the frequency from the TEOM can be analyzed properly.

Ung? Var god dröj! En diskursanalys kring ungdomsarbetslöshet och fördröjd etablering på arbetsmarknaden

Youth unemployement in Sweden is at an all-time high, a fifth of all university and college students live in poverty and the number of young on welfare is increasing. This study attempts to answer the question of how youth deprivation has been made possible as a consequence of political action, focusing on youth unemployment.I critically examine the role of the Swedish government, the Swedish Labour Organisation (LO), and the various government departments through text analysis, in order to answer the question of how the current discourse on youth position in the labor market. Because youth unemployment is not an isolated phenomena the analysis covers several policy areas, such as education policy, labor market regulation and housing policy. I use discourse theories drawn from Laclau and Mouffe to expose how language is used as an instrument of political power.I conclude that the current situation is a result of policy choices where the young have fallen behind due to lack of political organization. Their situation is not problematized to the required degree and is often explained on an individual level rather than on a structural level..

DEN TILLHÖRIGHETSSKAPANDE MÖTESPLATSEN - Folkbiblioteket som mötesplats i svensk biblioteksdebatt

This Master's thesis concerns the public library as a public meeting place. Our aim has been to find out why and how the library as a social meeting place has been discussed within the Swedish library community and if there has been a constant core in the discussions from the mid 70's and up to the present day. In order to do this we apply a place and space-perspective. The result of the study is that the core of the said discussions concerning the library as a meeting place is to create belongingness. This is the reason why the library community has an interest in the public library's function as a meeting place with the idea that people, by using the public library in that aspect, may experience a feeling of belonging to the society.

Våld eller sex? - En litteraturstudie om den akademiska kontroversen kring våldtäkt

Partly due to its consequences on the physical and mental health but also because of women?s constant fear of being violated, rape is considered to be a public health issue. The theoretical aspects of rape were first discussed in the 1970?s mainly from the viewpoints of Susan Brownmiller and Michel Foucault. The aim of this literature study is to investigate the different perspectives on whether rape should be viewed as sex or violence, how the controversy has developed and what the authors claim that the different perspectives result in.

Effekter av CFTRinh-172, en ha?mmare av cystic fibrosis transmembrane conductance regulator, pa? tolvfingertarmens bikarbonat- och va?tskesekretion pa? so?vd ra?tta

Mixade vårdsalar, det vill säga där man blandar män och kvinnor, är något som förkommer på sjukhusen runt om i landet och bör uppmärksammas utifrån patientens perspektiv då denne är i beroendeställning av sjukvården och dess vårdmiljö. Det blir allt vanligare att sjukhusen idag har mixade vårdsalar, detta oftast på grund av tids- och platsbrist. Studiens syfte var att beskriva patienters upplevelser av att vårdas på mixad vårdsal på en akut sjukvårdsavdelning inom nedre kirurgi. Studien var kvalitativ med fenomenologisk ansats. En intervjustudie med femton patienter som hade vårdats på mixad vårdsal genomfördes och i resultatet framkom att majoriteten av patienterna upplevde det positivt att vårdas på mixad vårdsal.

Osäkerhet i energisimuleringar av flerbostadshus : Analys av fem nybyggnationer

Since energy simulations are used to verify that projected residential buildings will reach the current energy requirements it is important that the results are reliable.This report investigates the extent of uncertainty in energy simulations, estimates the causes of the uncertainty and its economic and environmental consequences.The method used in this report is based on three validation methods; empirical validation, analytical validation and comparative validation. The analysis was carried out for five multi-family dwellings in Uppsala with installed meters for energy measurements. One of these objects, Klockarlunden, was studied in more detail than the others.The results show that the deviations are between 10 and 29% for the studied objects, which means that the uncertainty is estimated to be at least 29%. All simulations underestimate the buildings need of energy. The simulation for Klockarlunden can predict the energy consumption to be within the range of 46-98 kWh/m2year with 90% confidence level based on the current uncertainty.

Nätdroger - Utmaningar för myndigheter, enskilt och inom ramen för samverkan

The aim of this study was to examine how the new established phenomenon of ?Internet drugs? causes challenges to organizations, both individually and in relation to collaboration. The study is based on qualitative semi-structured interviews with representatives from three organizations - one youth police unit, one medical addiction centre and four units working within social services. The theoretical approach that was used is theory about human service organizations, theory about collaboration and new institutional organizational theory. A conclusion is that the current drug classification is problematic and mainly challenging for the organizations that focus on prevention work and early interventions.

Centraliserad decentralisering? En studie av Marrakechprocessen och dess relation till global governance

The current debate regarding organizational strategies for sustainabledevelopment is influenced by the theory of global governance. Decentralizedstructures of the global society are taken to use in the realization of a sustainabledevelopment. New roles of transnational networks and partnerships raisesquestions of the ability of global governance to co-ordinate and implement longtermsolutions without assistance from centralized and hierarchic structures basedon government. The aim for this thesis is to illustrate the current conditions forwell-functioning networks of sustainable development and examine therelationship between global governance and government. Issues of participation,decision making and compliance are examined by a case study of the Marrakechprocess, a global process to support the implementation of sustainableconsumption and production.

Lågkonjunkturens påverkan på den svenska konsumentmarknadsföringen

The purpose of this essay is to analyze and understand the effects that a recession can have on a company?s marketing department. In times of a recession most companies have less means to promote their products to their target market and to build their brand. This means that cutting the marketing budget will show some effects on today?s way of marketing.

Mixed martial arts och boxning i Sverige

In 1970 professional boxing became illegal in Sweden and in 2009 the prohibition was removed.Just before both of these changes in the law there were debates in media where people argued forand against ilegalization. In the later debate the focus has shifted from professional boxing toinclude Mixed Martial Arts(MMA) as well. MMA was governed and bound by the same law asprofessional boxing.This purpose of this paper is to compare the debate in 1968-1969 with the debate in 2006. The twodebates resulted in two different outcomes, ilegalization of professional boxing in 1970 and thenlegalization of it 2009. Are there any reason for these differences? What is the reasoning behindthis? By using hegemonic masculinity as a guidance when examining the debates this paper istrying to understand how the discourse have changed over time.

The Reading the Mind in the Eyes Test - Revised Version á la Andersson & Karlsson

Introduction: The Reading the Mind in the Eyes Test is a widely used test for measuring aspects of social cognition. The aim of the present study was to provide results from a group of typically developing Swedish children (age 9-12) and to compare these results with children and adults in other Swedish and English studies, as well as results from a group of children with Asperger syndrome. Method: A Swedish version of the child version of the test was completed by 83 controls and by six children with Asperger syndrome. Results were compared between the two groups and with data from other studies. Results: The children in the current study did not differ on scores compared to children in the same age group in other studies.

Konflikthantering ur ett genusperspektiv : Hanterar kvinnor och män konflikter på olika sätt i olika situationer?

This study examines if men and women have different conflict resolution styles in different situations. There are several studies in this area, but the results are contradictive and they don?t take consideration to the context. The study is an explorative, quantitative examine in the form of a self-report questionnaire, where different scenarios are described. These scenarios are based on the parts of the context that this study focuses on; the relationship to the other part, the perception of treatment and the place where the conflict occurs.
