Detta arbete undersöker mobilt socialt nätverkande med smartphones som verktyg och har som syfte att belysa subjektiva värden i användandet hos en grupp så kallade ?early adopters?. Vi tittar närmare på hur samhället förändras i takt med att tekniken utvecklas, och ser till vilka konsekvenser och behov denna utveckling skapar. Vidare analyserar vi en grupp yrkesverksamma personer inom IT ? och Mediabranschen, som ligger i framkant vad gäller teknikanpassning.

Syftet med denna uppsats är att visa vilka faktorer som minskar användarnas vilja att använda mCommerce. Samt att visa utvecklare inom området vilka av dessa faktorer som har störst inverkan på att mCommerce inte används i större utsträckning. För att kunna göra denna studie har vi valt att undersöka vad som påverkar användandet av mCommerce i kundgruppen early-adopters. Denna undersökning har skett på Luleå tekniska universitet. De slutsatser vi kommit fram till är bland annat att behovet av att kunna utföra tjänsterna när som helst och var som helst verkar inte finnas.

I takt med att Internethandeln ökar och fler och fler använder smartphones, introduceras alternativa betallösningar pa? marknaden. En betalmetod som redan är etablerad a?r SMS-betalning. Med tanke pa? detta borde inte steget till att använda mobilbetalningstjänster i fysisk butik vara så stort.

Traditionell marknadsföring och reklam i tidningar och på TV minskar, medan tilltron till word of mouth som informationskälla har ökat. Forskare har gjort en differentiering mellan så kallad organisk och konstruerad word of mouth där skillnaden ligger i att den förstnämnda uppstår naturligt ur en positiv upplevelse, medan den senare varianten sker som ett resultat av ett ekonomiskt utbyte med en tredje part. Det största företaget i Sverige som använder sig av konstruerad word of mouth som marknadsföringsstrategi är det webbaserade företaget Buzzador. Få studier har gjorts gällande word of mouth ur den utövande individens perspektiv. Syftet med denna studie är således att kvalitativt intervjua privatpersoner som är medlemmar på Buzzador för att undersöka deras upplevelser av tjänsten och uppkomsten av eventuella dilemman rörande deltagandet i konstruerad word of mouth.

We derive the equation linking the Weyl tensor with its Lanczos potential, called the Weyl-Lanczos equation, in 1+3 covariant formalism for perfect fluid Bianchi type I spacetime and find an explicit expression for a Lanczos potential of the Weyl tensor in these spacetimes. To achieve this, we first need to derive the covariant decomposition of the Lanczos potential in this formalism. We also study an example by Novello and Velloso and derive their Lanczos potential in shear-free, irrotational perfect fluid spacetimes from a particular ansatz in 1+3 covariant formalism. The existence of the Lanczos potential is in some ways analogous to the vector potential in electromagnetic theory. Therefore, we also derive the electromagnetic potential equation in 1+3 covariant formalism for a general spacetime.

This paper analyses the potential extent of labour mobility in the European Union after the eastern enlargement that took place in 2004, but focuses on movements from the 10 new member countries to the old EU -members. In this study, a number of economic models are used to investigate if there is a large potential for labour mobility in the enlarged EU and also if this potential has large effects on mobility in reality. The potential for labour mobility is, to a large extent, discussed in terms of theoretical migrating incitements for workers and different types of labour migration obstacles. Many factors indicate that such large potential for migration actually exists, mainly due to high difference in wages and unemployment and because of the common EU market. At the same time, the presence of natural and constructed obstacles is likely to restrict migration for a long period of time..

Målet med denna undersökning är att teoretiskt undersöka den vatten/litiumbromidbaserade absorptionsprocessens potential ombord fartyg då processen enbart drivs av huvudmaskinens högtemperaturkylvatten. Undersökningen genomförs teoretiskt mot tre olika fartyg samt Sjöfartshögskolan i Kalmars maskinrumssimulator. För vardera fartyg undersöks driftenergikällan och kylbehovet ombord. Med det som underlag dras en slutsats om den vatten/ litiumbromidbaserade absorptionsprocessens potential ombord fartyget. Fartygens resultat ligger till grund för slutsatsen.

The aim of this thesis is to investigate the electric solar potential on the Swedish island Gotland. The Gotlandic habitations have been divided into four house categories. For each category energy demand, roof area, geographic orientation androof tilt have been decided. Solar radiation data have been collected from the Swedish solar radiation model STRÅNG (STRÅNG, 2012).The buildings characteristics and the solar radiation have been used as input values in common solar formulas, the solar potential for each building category have been summed up to a total electric solar potential for the region.The electric solar potential on Gotland was calculated to 242 GWh/year with solar data from 2010. Gotlands largest city, Visby, is marked as cultural heritage by UNESCO (UNESCO, 2012).

The mobile jukebox is an idea for a new kind of smartphone application that would allow users to dictate the music playing at various establishments. The mobile nature of the innovation allows for the possibility of a more ubiquitous service. Conducting a quantitative as well a qualitative study, the authors have found significant interest in this innovation service among potential users and potential distributors of the service. Furthermore, it is shown what aspects are important for decision makers to make a decision on whether to integrate the service into the operation of potential distributors of the service.  .

Vårt arbete syftar till att studera två övergripande tillvägagångssätt gällande annonsering vid en nylansering för att avgöra när det ena tillvägagångssättet förespråkas framför det andra. En kvalitativ studie i form av 4 individuella delvis öppna djupintervjuer har genomförts genom att utgå från en tolkningsbaserad ansats. Intervjuerna har genomförts med personer från en mediebyrå, reklambyrå, ett högteknologiskt företag samt en mediekanal. Teorier om produktlivscykeln, lansering, målgrupp, självkoncept, typ av produkt samt reklamens utformning behandlas i studien. De slutsatser som kan dras är att det inte finns någon generell ideal tidpunkt för annonserig vid lansering av en ny produkt.

Intelligent IT-based solutions, often called Smart Grids, are considered to be the future balancers of renewable energy sources. One area within the Smart Grid concept is called demand response, which is focused on making customers more consumption flexible by making them more active in their consumption. In this thesis the aim is to analyze a business model by investigating the income potential for a demand response solution as well as its market potential. This has been done through literature studies, interviews and development of a computational model.The use of 5000 households with flexible consumption can provide a cost reduction of 17.2% or 2.4 million SEK for a balance responsible party during an average year. If the solution is used to make strategic bids on the regulation markets the study indicates that the largest potential for revenues lies within this strategy.

The report is a result of a bachelor thesis at the department of business administration, School of Business, Economics and Law, Gothenburg University, spring term 2008. The study examines the potential return of Swedish Venture Capital firms? Cleantech investments, carried out in 2006 and 2007, compared to the return on their other investments.The study has identified a number of factors affecting the return. These have been classified within three areas: the characteristics of the Venture Capital investment, the characteristics of the Venture Capital firm and the market potential for Cleantech. The impacts on potential return for these factors are investigated by means of an interview survey with 18 Swedish Venture Capital firm covering 45 investments in Cleantech.Our research indicates a worse potential return on Cleantech investments compared to other investments.

This essay examines computer and video games and their capacity of being useful in teaching sessions. Focus is being put at a possible pedagogical potential and how it is being expressed in games mechanics. To get answers on these subjects? studies by Professor James Paul Gee and Jesse Schell is used together in creating a model for analysis. With this model together with a narrative analysis this essay hopes to give clarifications on if a pedagogical potential is present and if so, how it is being expressed.Studies in this paper shows that a pedagogical potential is overall present in used material.

Former studies have shown that a considerable part of industries? energy usage can stem from idle times in the production. This thesis, carried out at Siemens Industry sector, evaluates the potential for using the control system to automatically put machines into energy saving mode during idle times. The main part of the thesis consists of a case study performed on machine tools at a Scania production site in Södertälje. Through load measurements the potential for energy savings was determined.The results show that there is a great potential for energy savings during idle times at the site.
