Fritt søk med FAST søkemotor integrert i PostgreSQL relasjonsdatabase

Focus of this thesis is the relationship between databases and information retrieval systems. As a background, the first part consists of a general presentation of databases and information retrieval systems and some examples of already existing efforts to combine the two. While these examples typically have expanded either a database system or an IRS to obtain multi-functionality, we have made an effort of bridging the two systems. Our prototype integrates FDS (Fast Data Search) into the PostgreSQL database management system as a new index access method. FDS is a powerful and scalable commercial enterprise search platform using a typical search engine query language. PostgreSQL, being open source and a general basis for research, lends itself well to customization. The new index access method provides the database with powerful free text capabilities while retaining the power of the relational model for structured data. Preliminary results including a simple performance test verify the feasibility of the integration, and demonstrate the scalability of the prototype. Storage, indexing, updating and search functions are implemented, but ACID properties could not be guaranteed, because the external indexing system has no such guarantee. I also present a prototype for automatic extraction of related structured data in the relational database to XML. Combining these two prototypes by allowing the extracted information to be searched using the full text index, makes it possible to search the database without knowledge of the underlying database scheme. Finally I discuss potential expansions of our implementation by indexing other data than text, multicolumn-indexing and moving complex evaluation from PostgreSQL to FDS, and suggest how this could be done.

"Viktig informasjon om rettigheter og plikter!” : en diskursanalyse av NAVs informasjonsbrosjyre om arbeidsavklaringspenger

Masteroppgave i psykisk helsearbeid ME504 Universitetet i Agder 2013The study is based on a qualitative study of the information brochure of WorkWelfare Allowance (AAP) authored by The Norwegian Labour and WelfareAdministration (Nav). The aim of the study is to uncover various discourses hidden inthe text. The investigation is based on the clients introduction to his own economicalbenefit in the information brochure of AAP. The research question in the study iswhich discourses are made visible in the text.The study is based on critical discourse analysis. The method identifies and highlightsmeaningful expressions appearing in the prospectus, both linguistic structures andconsequential as it embodies into social practice. The study demonstrate howlanguage and society are mutually dependent, and emphesizes the power relations thatmay be underlying the current social practice. The power governed and executed byNav constitutes a central theme throughout this thesis.The key discourses in the study are: a) the discourse of command, b) the discourse ofexpertise, - and c) the discourse of disipline -the absence og client participation.The study's results are discussed with implications and consequences of the lack offocus on client participation. The study concludes with reflections upon increasedclient participation focus and the concequences of using a more ethical soud languagein the text, as a shift towards more democratic perspectives

Maternal eating disorders influence sex ratio at birth

We explored sex ratio at birth, defined as the proportion of male live births, in women with anorexia nervosa, bulimia nervosa, binge eating disorder, and eating disorders not otherwise specified-purging type (EDNOS-P) relative to a referent group in a large population based sample of 38,340 pregnant women in Norway. Poisson regressions were adjusted for mother’s age, pre-pregnancy BMI, lifetime smoking status, maternal education, income, marital status, gestational age, and parity. Lower proportions of male live births were observed in the anorexia and bulimia groups, while binge eating disorder and EDNOS-P were associated with a higher proportion of male births. These data suggest that maternal eating disorders may influence offspring sex and that the direction of effect may vary by eating disorder subtype. If confirmed, this finding could provide evidence in formulating hypotheses regarding the consequences of eating disorders and determinants of sex ratio at birth
