The original promise behind the Internet Protocol was to deliver data from a sender to the receiver using a best-effort approach. This means that the protocol makes no guarantees except that it will try to deliver the data to the destination. If some problem occurs the packet may be discarded by the network without any notice. No guarantees are made regarding the time it takes to deliver the data, the rate at which data will be delivered or if data is delivered in the same order it was sent. The best-effort approach is arguably the reason behind the success of the Internet Protocol and is what makes IP scalable to networks the size of the Internet.

This piece of work develops a solution that automates protection against software keystroke loggers. Keystroke loggers can be used illegally to register a user's keystrokes and in that way acquire sensitive information. The solution was tested on two different networks and the efficiency was measured. The network represents an enterprise network that uses the operating system Windows along with the directory service Active Directory. A script was developed to solve the automation matter.

The DISA method is a universal program developed for teenage girls to prevent depression. The program includes cognitive behavioral techniques are suppose to change negative pattern of thinking, give practice of communication, strategies of problem solution and exercises to strengthen the social network. The purpose of this study is to find out how a group of teenage boys were affected by the DISA program and what factors that may have impacted the outcome. Material from three different studies have been used, a quantitative study in terms of data from self-assessment form CES-D, materials from two semi-structured focus group interviews with the boys and material from a questionnaire filled out by the boys on two occasions during the DISA method. The result of the CES-D indicates that the boys had less depressive symptoms after the final group meeting compared to the first group meeting and also a year later. Analysis of the material from focus group interviews and questionnaire have been made from a communication theory and systems theory perspective and indicate a shift to greater cohesion in the group and demonstrates that communication between the boy-group and group leaders had importance for the outcome.

?The modern library in the network society?A study of cultural politicians and librarians opinions about libraries' use of social mediaSocial media is becoming more and more interacted in our daily lives and Carlsson (2013) argues that today's libraries have undergone major challenges in the digital information technology's entry in the library arena. The new technology has led to sum up in one question: how a library should relate to the digital information technology, the issue has applied in particular the social communications media, such as Facebook, Twitter and more. The purpose of this paper is to examine the culture of politicians and librarians 'perceptions of public libraries' use of social media linked to the libraries and their democracy promotion efforts.

The theses discuss information seeking with a focus on Google and social networks. Students attending the librarian program in Lund have been examined by means of two methods; diaries and information horizons, where they had to solve a specific assignment. The information horizon as a method contributes to getting a structural perspective on the information search process instead of viewing information search as a procedure. Information horizons use social network analysis.The aim of the theses is to investigate the importance of the social network in information search, with a particular focus on Google as a search tool. Our hypothesis is that Google acts as a compensator to the social network when the students search for information and in the educational program.The research indicates that there is no direct correlation between usage of the social network and usage of Google.

Verksamheten ombord på fartyg blir mer beroende av datakommunikation och många av arbetsuppgifterna ombord underlättas genom att besättningen kan nå information lagrad på annan plats. Fartygens bredbandsanslutning sker till största delen via satellitkommunikation där långa avstånd och begränsad datahastighet resulterar i att datakommunikationen blir ineffektiv. I denna studie undersöks vilken prestandaförbättring som utrustning för nätverksoptimering kan innebära för långsamma WAN-förbindelser via satellit. Undersökningen visade att det största problemet med anslutningar via satellit är den signalfördröjning som uppkommer vid långa sändningsavstånd. Detta medför att det blir prestandaproblem för datatrafiken och användare upplever anslutningen som långsam.

In this paper, a small business network with around 30 users is analyzed with respect to security, performance and usability. Based on this analysis, two suggestions on how to solve the problems listed are given. The first suggestion focus on keeping a low budget, while the other tries to deal with the problems more thoroughly. One advantage of the first suggestion is, in addition to not straining the company's budget more than nessecary, it does not involve too great changes in the way the network is used and administered. On the other hand, the smaller budget leads to certain compromises, and there is a risk that similar problems occur again if, for example, the company would grow.

The aim of this study has been to examine the role of control mechanisms when it comes to building relationships in a small business network. In order to reach this goal, we have performed a case study of a Swedish supplier of machines to the engineering industry, which acts as the exclusive representative of a foreign manufacturer on the Swedish market. Main results: A number of control mechanisms, both formal and informal, could be identified in the network. Their specific use, as well as relative importance differ between different actors in the network. In general, the importance of formal control mechanisms decreases as the relationship evolves over time and the importance of informal ones, mainly trust, increases in a corresponding manner..
