Finnes: flata. Sökes: information. Om lesbiska, informationsbehov och ämnesbestämning av skönlitteratur.

The aim of this Masters thesis is, partly, to examine the information needs of lesbians: what discernable information needs they have, how they seek information and which information sources they use. The purpose is also to examine what part fiction plays regarding the information needs mentioned above and how fiction indexing could improve retrieval. The study is conducted through ten qualitative interviews with lesbians as well as through textual analysis. The theoretical framework includes queer theory and theory concerning information needs and uses. The results indicate that lesbians have evident information needs that mostly concern identity.

The black-and-white colobus monkeys (Colobus angolensis palliatus) of Diani forest, Kenya : behavioural responses to habitat fragmentation

The loss of habitat is one of the greatest threats to global biodiversity today. Consequences to a species inhabiting fragmented habitats include: group size changes, altered diets and altered foraging behaviours. In my study I observed Colobus anlgolensis palliatus troops living in the forests of Diani, a highly developed area on the Kenyan coast. I looked for differences in behaviours between three troops inhabiting pristine forest patches and three troops inhabiting highly degraded forest areas. I used focal animal sampling with instantaneous sample points.

Information ur ett poststrukturalistiskt perspektiv: En diskussion kring informationsrelaterade teorier hos Mark C. Taylor, Jacques Derrida och Michel Foucault.

Defining the concept of information has long been the subject of debate within Information Science (IS) and new challenges are constantly presented by new scientific discoveries and new theoretical positions. It is, nevertheless, of key importance for any academic discipline to find definitions on which there is a consensus. The paper therefore aims to clarify the relevance of one of these new theoretical approaches for IS, namely poststructuralism. It does so by describing the theories found in the writings of poststructuralists Mark C. Taylor, Jacques Derrida and Michel Foucault, and discussing their relevance for the three definitions of information suggested by Michael Buckland (Information-as-knowledge, Information-as thing and Information-as-process), thereby answering the following questions: What relevance does Mark C.

Vad förklarar variationer i frivillig information?

There is an increased pressure for firms to provide the financial market with additional information. Such disclosure is attached with different kinds of costs. In spite of these costs, and in spite of increased mandatory disclosures, firms choose to voluntary disclosure financial information to analysts and others. This indicates that firms also benefit from providing additional information. The subjects of this study is 431 annual reports from firms listed at the Stockholm Stock Exchange for 2002 and 2005 and the objective is to survey factors that can explain variations in firms? voluntary disclosure.

Feeding preferences and foraging in Larvae of Manduca sexta and Spodoptera littoralis : a laboratory study based on olfaction

Larvae of Lepidopteran Manduca sexta and Spodoptera littoralis are pests of economical importance in several horticultural and agricultural crops. Knowledge of insect feeding preferences and behavior is crucial in order to find economically and ecologically sustainable solutions to the problems caused by these herbivores. The aim of this thesis was to study the behavior and the induced feeding preferences in larvae of M. sexta and S. littoralis when reared on certain host plants. The hypothesis was that larvae of M. sexta would have an innate preference for plants of the Solanaceae family and therefore discriminate the previously experienced nonhost when faced with the choice between a true host and the previous food source.

Stuxnet-attacken mot Iran : Strukturell realism i informationsrevolutionens tidsålder

This study aims to explain the Stuxnet-attack against Iran in 2009-2010 by using the IR-theory of structural realism. By doing so the theory also faces the challenge of the impact of the information revolution on security and international relations. The structural realism that is at hand is that of Kenneth Waltz and his Theory of International Politics from 1979.The study reaches the conclusion that Waltzs focus on the structure of the international system and the distribution of capabilities applies well to the case of Stuxnet as a cyber attack. The creators of the sophisticated Stuxnet, USA and Israel, also indicates that when it comes to this certain aspect of the information revolution and IR, states seem to still be the main actor. Finally the character of one of the major features of the Stuxnet-attack; the internet, is shown to have an anarchic structure that fits well as an extension of the realist view of the international system..

Advantages and disadvantages of different observation methods on a troop of wild olive baboons at a river in Southern Kenya

Every observation method has its advantages and disadvantages and a well-adopted method gives more reliable results. Factors affecting the choice of the most appropriate methods for recording foraging behaviours include species, group size, environment, seasons and age. The focus for this study was to determine which method is most appropriate for studying the foraging behaviour of a troop of 89 olive baboons (Papio anubis) living in a riverine forest by the Southern Ewaso Ng'iro River by Lale'enok Resource Centre in Kenya. To determine this, a literature study was carried out to compare methods from monkeys and apes. I found instantaneous sampling was the most common method with intervals of 5 minutes in most cited studies.

Captureteorin : Regleringar och konsten att fånga politiska beslut i den demokratiska processen tillämpad på den svenska läkemedelsmarknaden

The Capturetheory wants to give an alternative explanation for the need of regulation. From this point if view the government does not have enough information to make an optimal regulation. There is a possibility for different interest groups to take advantage of the political arena by rent- seeking behaviour. An industry may be willing to be regulated to protect itself from competition. The objective of this paper is to account for the pros and cons of the theory of regulatory capture and also if it can be applied to the Swedish market of pharmaceuticals.

Tankar kring informationssökning: hur ser uppsatsstudenter på BHS på sin egen informationssökning?

The purpose of this thesis is to investigate how students writing their master thesis seek information, how they reason about their information seeking behaviour and how their studies in LIS could have affected their information seeking behaviour. The result was analysed with Roger Säljö?s theory about the sociocultural perspective about how individuals learn in relation to their context and the social practice that they act in. The following conclusions were drawn from analysing the result. The students didn?t really reflect over their information seeking behaviour.
