Librarians must continue their traditional roles as privacy rights activists and intellectual freedom upholders into the digital age, and across electronic information sources, including social media fora. Social media is quickly becoming a major source of information and center for information seeking, and librarians have an opportunity to promote and help shape social media policies that protect users privacy and assure that users can seek information without inhibition. One way librarians can be involved in the promotion of online privacy is by joining the social media user rights movement and advocating terms of use agreements that protect information seekers that follow the "Privacy by Design" model created by Ann Cavoukian, Ph.D.

A sequence of actions in the world have influenced the information science, one of these actions is the lateral movement in how companies use their IT-systems. IT-systems today, in comparison to before, are used by companies to improve their relationship with their customers. Every year a big amount of money is spent on developing and improving IT-systems. That is why it is important to develop and create IT-systems that are clear, and which encourage, enable and simplify a users action. There are criteria to use in actability and eTjnstetydlighet. I have in this thesis used acknowledged criteria for actability and eTjnstetydlighet to analyze two IT-systems that are equal to each other. This is to show how companies can develop and adjust their IT-system so that they will match todays point of view. I have also in this thesis chosen to evaluate the usage of criteria for eTjnstetydlighet and that is because no one has done that before. The result of this thesis gave Monster and Proffice measures for how to develop their IT-systems. The result of this thesis also gave indications of fuzziness when using criteria for eTjnstetydlighet, however, I was able to use the criteria the way they were supposed to be used to fulfill their purpose.

Thep-median model is used to locate P facilities to serve a geographically distributed population. Conventionally, it is assumed that the population always travels to the nearest facility. Drezner and Drezner (2006, 2007) provide three arguments on why this assumption might be incorrect, and they introduce the extended the gravity p-median model to relax the assumption. We favour the gravity p-median model, but we note that in an applied setting, Drezner and Drezners arguments are incomplete. In this communication, we point at the existence of a fourth compelling argument for the gravity p-median model.

Location Models are usedfor planning the location of multiple service centers in order to serve a geographicallydistributed population. A cornerstone of such models is the measure of distancebetween the service center and a set of demand points, viz, the location of thepopulation (customers, pupils, patients and so on). Theoretical as well asempirical evidence support the current practice of using the Euclidian distancein metropolitan areas. In this paper, we argue and provide empirical evidencethat such a measure is misleading once the Location Models are applied to ruralareas with heterogeneous transport networks. This paper stems from the problemof finding an optimal allocation of a pre-specified number of hospitals in alarge Swedish region with a low population density. We conclude that the Euclidianand the network distances based on a homogenous network (equal travel costs inthe whole network) give approximately the same optimums. However networkdistances calculated from a heterogeneous network (different travel costs indifferent parts of the network) give widely different optimums when the numberof hospitals increases. In terms ofaccessibility we find that the recent closure of hospitals and the in-optimallocation of the remaining ones has increased the average travel distance by 75%for the population. Finally, aggregation the population misplaces the hospitalsby on average 10 km.

A customer is presumed to gravitate to a facility by the distance to it and the attractiveness of it. However regarding the location of the facility, the presumption is that the customer opts for the shortest route to the nearest facility.This paradox was recently solved by the introduction of the gravity p-median model. The model is yet to be implemented and tested empirically. We implemented the model in an empirical problem of locating locksmiths, vehicle inspections, and retail stores ofv ehicle spare-parts, and we compared the solutions with those of the p-median model. We found the gravity p-median model to be of limited use for the problem of locating facilities as it either gives solutions similar to the p-median model, or it gives unstable solutions due to a non-concave objective function.
