The purpose of this thesis is to compare five different ranking algorithms for query expansion. The algorithms compared are f4, f4mod, porter, wpq, and emim. This is done using a TREC collection, a selection of topics, and relevance judgements. Relative recall is measured before and after the expansion of the query. The study shows that all of the algorithms manage to increase the relative recall, f4 being the one most successful..

The master's thesis investigates how the concept traditional knowledge is represented by international organizations that are influential in development work and policy making. Departing from a theoretical framework drawing on Michel Foucault, constructed aspects of knowledge and the power relations knowledge production implies are highlighted.A recent interest within library and information science and practice to document this kind of knowledge raises questions about how traditional knowledge differs from other forms of knowledge and how knowledge organizational tools can be applied. Investigations, which critically explore the concept traditional knowledge, the power relations the concept creates as well as the interests and purposes it serves, have been surprisingly absent within the discipline. The focus in this master's thesis is how traditional knowledge is conceptualized by international organizations. A discourse analytical approach reveals the power relations that are inherent in their descriptions of traditional knowledge and how they describe the relevance of the concept for their work.

We have chosen to use semi structurized interviews to achieve our goal of reaching the clients experience of long-term income support dependency. The study consists of interviews of six clients whose answers have been analyzed through appliance of Kielhofner´s Model of human occupation, Scheff´s Shame in self and society.   Our results show regarding, 1) the factor health that long-term income support dependency may elevate the risk of illness and less experienced options of possibilities to act. 2) regarding the factor goal setting, that goals may be inefficiently used during social work with long-term income support dependent clients and may result in a disorganized relationship between client and social worker in the sense of making the parties pull in opposite direction. 3) regarding the factor motivation, that long-term income support dependency and the living with the emotion of shame elevates the risk of maintaining a negative image of oneself that limits the willpower to assimilate new knowledge and/or skills.

This B.Sc. Thesis examines how Swedish Large Cap companies communicate CSR in social media. We describe the current state of CSR communication in four different social media channels, Twitter, Youtube, Facebook, and blogs. This research, supported by interviews with stakeholders and a quantitative survey, analyses the potential risks and benefits from communicating CSR via social media and provides concrete advice on the development of a CSR communication strategy for social media. Although some benefits have been realized, many companies have failed to truly reap the potential benefits from an effective social media strategy for CSR.

Densification is one of the urban visions for sustainable development - a vision that has become a part of the solution to the unsustainable sake dilemma. With the dense city land will be saved, energy consumption reduced and social cohesion improved. The dense city is considered to be ecologically, economically and socially sustainable. Applying an urban design concept has thus proven to be problematic. Density has been found to be a complex concept which is far more complicated than measuring how much built surface that needs to be covered. It is also not disputed what different degrees of densification mean and whether densification in itself is sustainable.
