New forms of Information and Communication Technologies (ICTs) have become more influential in development contexts. The concept of ?The Digital Divide? points at a large division between rich and poor countries regarding access to ICTs. Critics say that the debate concerning this topic for far too long has focused mainly on the technology itself rather than social factors which impact social inclusion and development. Scholars agree that ICTs holds a tremendous potential, but how is this implemented in development contexts and how can it be used with more sensitivity towards local preconditions and social aspects?This paper aims to examine how ICTs are being used in the context of development within an India based organisation for women called SEWA (Self Employed Women?s Association).
Fysikalisk modellering av klimat i entreprenadmaskin
This masters thesis concerns a modeling project performed at Volvo Technology in Gothenburg, Sweden. The main purpose of the project has been to develop a physical model of the climate in construction vehicles that later on can be used in the development of an electronic climate controller. The focus of the work has been on one type of wheel loader and one type of excavator. The temperature inside the compartment has been set equal to the notion climate. With physical theories about air flow and heat transfer in respect, relations between the components in the climate unit and the compartment has been calculated.
Det första mötet : Jämförelser av första-gången-händelser rapporterade av mödrar och fäder vars barn vårdats enligt kängurumetoden på två neonatalavdelningar
Aim: Compare occurrences of first-time-events reported by mothers and fathers with children at high tech NICU according to kangaroo-mother-care method in two university hospitals. Method: Descriptive, quantitative design. Fourty-five couples of parents, with premature children born and cared for at university hospitals in Uppsala or Örebro, answered questionnaires about first-time-events: interaction-events, measures-of-care-events and sleeping-place-events. Results: All differences regarding the children?s age at first-time-events showed Uppsala-children to be younger than Örebro-children. Interaction-events were reported first in children?s lives, measures-of-care-events and sleeping-place-events later.
Den ständiga förändringen : En komparativ studie i vinstdrivande fo?retag och ideella organisationers varuma?rkesarbete pa? sociala medier
AbstractTitle: The constant change - A comparative study of profit companies and nonprofit organizations' brand management through social mediaAuthor: Agnes Nobel & Matilda VallgrenTutor: Daniel LövgrenPurpose: The purpose of this thesis was to study profit companies and nonprofit organizations? branding and strategic communication on social media. If social media has supported with new interaction with stakeholders and hence affected the branding work. Also if there are any differences between profit companies and nonprofit organizations.Method/Material: The method that is used in the article is a qualitative research. The research is based on conversations interviews conducted with eight organizations, four profit companies and four nonprofit organizations.Main results: The main result showed that all organizations are actively involved with social media in their strategic communication when in order to increase the interaction with stakeholders and thus strengthen their brand identity. It turned out that all organizations have not adapted the brand to social media, but worked with the organizations values ??and only applied the trademark on social media.

Electrical track system : Utveckling av ett nytt system, innefattande elektrisk golvlist och uttag, som medger flytt av de traditionellt fasta vägguttagen
This degree project concludes the Innovation and Design Engineering programme at Karlstad University. The project was carried out by David Brocker, Erik Hallberg and Andreas Hertzman during the spring of 2006 and corresponded to 15 weeks of work per student. Assigner was Martin Larsson at Arexor and instructor at Karlstad University was Monica Jakobsson.Arexor has a patent to a construction of an electrical skirting board with moveable wall sockets, called Electrical Track System. The lowest parts of the interior walls along the floor are today almost always covered by a conventional skirting board. Arexors patented product replaces that with the possibility to move and increase the number of wall sockets by choice along an electrical skirting board.
Faktorer som påverkar användningen av säkerhetsprogram: en studie om antispionprogram
För att privatpersoner ska ha en möjlighet att skydda sig mot olika former av säkerhetshot finns det programvaror vars syfte är att agera mot dessa säkerhetshot. Programvaror som skyddar mot logiska säkerhetshot är exempelvis brandväggar, antivirusprogram och antispionprogram. Säkerhetshot i form av spionprogram är en nyare företeelse och är i de flesta fall direkt riktade mot privatpersoner. Trots att undersökningar har visat att privatpersoner är medvetna om denna form av säkerhetshot är det få som vidtar åtgärder mot programmen. Syftet med undersökningen är därför att studera vilka faktorer som påverkar användningen av antispionprogram bland privatpersoner.
Hållfasthetsegenskaper i gjutjärn : tensile properties of cast iron
In the last few years people have become more and more aware of how humanity is affecting the climate. In the direction of reducing the greenhouse gases is to design engines with higher tensile properties and reduced weight, in order to achieve lower fuel consumption and cleaner fuel incineration in today's truck engines.In order to achieve these requirements it?s necessary to increase the combustion pressure in the engine. This requires higher tensile properties and high thermal conductivity of the engine material. The department of Component Technology at the University of Jönköping in collaboration with Volvo Powertrain AB, Scania CV AB and DAROS Piston Rings AB has been commissioned to develop this material and to find knowledge of material properties used in truck engines and piston rings used for marine applications.The purpose with this work is to analyze the tensile properties of a series of cast iron, cast under different metallurgical conditions.Four different series of cast irons have been analyzed from four points of view, carbon concentration, nodularity, amount inoculation and cooling rate.After the tensile test all specimen data was analyzed in a mathematic calculation program called Matlab 2006a.

In Sweden there is only one law, which allows preferential treatment ? the law of equal opportunities. This law prohibits discrimination between women and men. The profession of camera operator and editor have been viewed as masculine in accordance to heavy lifting and high technology, this considering being hindrance to women.
Nätpiraternas ideologi : En retorisk analys av Piratbyråns webbsite
AbstractPurpose/Aim: To study how Piratbyrån argues for a free distribution of information and culture products and to find a possible ideological explanation for their argumentation.Method/Material: I have used a rhetorical analysis to study and describe Piratbyrån´s website, a website that promotes free distribution of information and culture products. I have done so to find out how Piratbyrån argues for a free distribution and to find out what ideological foundation their argumentation is based on.Main results: The main results of the study show that Piratbyrån uses a variety of rhetorical techniques depending on the subject and purpose of the analyzed text. Their main arguments both promote their own thesis and argue against the copyright industry. The main part of the argumentation is based on logical and factual arguments, but parts of it also rely on an emotional appeal to the reader?s heart in order to persuade.

Membranbioreaktorteknik- en framtida lösning på Lundåkraverket? : Membrane bioreactors- A future solution at Lundåkra wastewater treatment plant?
Membrane bioreactors (MBR) combined with biological phosphorous treatment (Bio-P) has been investigated if that could be an alternative to the future expansion with conventional active sludge treatment at Lundåkra wastewater treatment plant (WWTP) in the proximity of Landskrona, Sweden.The results showed that the surface demand in the biological treatment will be reduced with 67% with the MBR-alternative compared to a conventional activated sludge process. The nutrient removal in the MBR-solution was decreased or unchanged for nitrogen-, phosphorous- and organic parameters. However, the energy demand will increase with an estimated cost of approximately 1 million SEK annually. Moreover, the extra chemical consumption is estimated to cost 370 000 SEK annually.The disturbances caused by filamentous bacteria such as sludge dispersal could be resolved with MBR-technology because the membranes are not affected by these organisms. The Bio-P process combined with MBR-technology works if the wastewater recirculates from the membranes to an aerobic zone.In the proposal, there will be a new pre-treatment step, for instance hole screens.
