Denna rapport beskriver utvecklingen av en Instant Messaging klient som implementerats som en språkwrapper. Klienten använder ett känt öppen källkods-bibliotek vid namn libGaim för att få tillgång till Instant Messaging tjänster. Klienten fungerar som en språkwrapper till detta bibliotek, och låter andra applikationer nyttja biblioteket genom ett databasgränssnitt. Arbetet har utförts åt och hos Evolve i Karlstad. Systemet som utvecklats klarar att hantera vanliga Instant Messaging-funktioner så som uppkoppling av konto, nedkoppling, ändring av status, visa kompisikoner, och hämtning av information angående kompisar. I beskrivandet av arbetet med detta system ges bakgrundsinformation angående wrappers och Instant Messaging, och dessutom angående de verktyg och metoder som använts likt byggverktyget SCons och utvecklingsmetoden eXtreme Programming. Valet av lösning och design presenteras. Som en del av arbetet undersöks språkwrappers med hjälp av av ett antal tester. Dessa tester visade på vilka skillnader som kan väntas beroende på valet av språkwrapper. En språkgenerisk språkwrapper (som skapar ett gränssnitt mot flera språk) behöver inte utgöra någon större prestandaoverhead jämfört med en språkstatisk språkwrapper (som skapar ett gränssnitt mot ett språk). Resultatet av arbetet blev ett system som Evolve blev nöjda med och som uppfyllde alla krav som ställdes, antingen fullständigt eller delvis. / This report describes the development of an Instant Messaging client that is implemented as a language wrapper. The client uses a well known open source library, known as libGaim, to access Instant Messaging services. The client works as a language wrapper for this library, and allows other applications to use the library by means of a database interface. The work has been carried out at and for Evolve in Karlstad. The system that has been developed can handle common Instant Messaging operations such as connecting a user account, disconnecting, changing an accounts status, showing buddy icons, and collecting information regarding buddies. In the description of the work with this system, background information is given regarding wrappers and Instant Messaging, and also regarding the tools and methods used, such as the build tool SCons and the development method eXtreme Programming. The choice of solution and design is presented. As a part of the work, language wrappers are evaluated using a number of tests. These tests show the differences that can be expected depending on the choice of language wrapper. A language generic language wrapper (which creates an interface for several languages) need not imply any significant performance overhead compared to a language static language wrapper (which creates an interface towards one language). The result of the work we have done was a system that Evolve was pleased with and that satisfies all the requirements, either completely or partially.

Location-based service (LBS) is a geographical location-related service that provides highly personalized services for users. It is a platform for network operators to provide new and innovative ways of increasing profits from new services. With the rapidly growing trend toward LBS, there is a need for standard LBS protocols. This thesis started with introducing the Internet Engineering Task Force GEOPRIV working group, which endeavors to provide standard LBS protocols capable of transferring geographic location information for diverse location-aware applications. Through careful observation, it was found that Session Initiation Protocol (SIP) is well suited to the GEOPRIV requirements. The aim of this research was therefore to explore the possibility of the integration of LBS and the SIP protocol and, to some extent fulfill the GEOPRIV requirements.

The introduction of the Internet and computers into the work environment have changed the news industry. New models of revenues for spreading the news, and the reachability and accessibility of the news has grown tremendously. These implications have influenced the way media company’s employees have to work, from multi-skilling to communicating with each other efficiently. This research seeks to investigate the current state of the internal communication flow in a Swedish media company called Hallpressen AB and to find opportunities for improving the internal communication flow inside the company. In order to fully understand the existing situation in the company, the authors observed nine of the company’s departments, held 14 interviews with managers and executive committee members, and conducted two focus groups. Based on the data collection, the authors created a communication channel model of the existing communication inside the media company, and performed a qualitative content analysis to summarize the findings from the observations and interviews. The focus groups were performed in order to examine an existing communication tool called “Slack”, and to understand the general perception that the company’s employees held of it. From the findings, the authors suggested possible improvements for the company’s internal communication flows. First, what could be improved in the management of communication inside the company, such as opening of a communication department or hiring an internal communicator. Second, what could be improved in already existing communication channels, such as creation of special part on the intranet for every department and etc.

<p>There are few empirical studies about instant messaging, and the measurements used are somewhat diverse. The main purpose of this study was to investigate if depression and loneliness differed in relation to instant message habits among young adolescents. Special focus was also on motivation behind, and time spent on instantmessaging. The study was conducted using a self report questionnaire,using 3 factors for motivation and 8 items to measure time. The 365 participants were between ages 12 and 16. The study found that depression and loneliness differed in many ways depending on what measurement compared with. The conclusion drawn is that future studies have to use more precise measurements.</p> / <p>Det finns få empiriska studier om chattande och de mått som används varierar.

Nowadays, the internet is an unseperatable part of human life and instant messaging software becomes an important role of communication channel. There are 40 million global IM registration popularity who use IM and billions of messages are sent everyday. In Taiwan, there are 6.5 million registration popularity and IM is the third important internet appilication, besides WWW and e-mail. As IM has become more and more important, there was few academic researchs published. We investigated consumer IM adoption behavior by focus group interview and structural equation model analysis. After holding a focus group interview, some antecedent of adopting IM was found out. Then we integrated technology acceptance model with media richness, computer self-efficacy and subjective norm as the antecedents of perceived usefulness(PU) and perceived ease of use(PEU) and analysised this structural equation model with LISREL. We found that subjective norm is an antecedent of PU, media richness and computer self-efficacy are PEU¡¦s antecedents. Finally, we made some suggestion for practice and other researchers base on the result.

Instant Messaging ¡]IM¡^ has becomes an important tool of communication. Currently, eighty percent of the Internet users use IM to communicate each other. This study uses the dimensions of performance expectancy and effort expectancy of the Unified Theory of Acceptance and Use of Technology and the interpersonal communication need to investigate factors that influence IM acceptance. There are 211 completed questionnaires were returned and analyzed. It¡¦s found that performance expectancy, effort expectancy, and interpersonal communication show significantly positive and significant impacts on IM users¡¦ intention. The intention significantly and positively affects their IM usage. According to the results, it¡¦s suggestted that IM software should make the IM more user-friendly and the software interface is not too complicated, so that users might feel that IM software is easy to use.
